Canary - Minimum of 2 birds were to be kept at the colliery for use in an emergency to detect carbon monoxide gas usually during a heating or fire or following an explosion. Generally there was an aviary with half a dozen or so usually supplied by a local breeder and they were well looked after and fed and watered by a member of the Safety staff. Canaries are easily bred and used to living in a cage unlike wild birds, however they only live three or four years like them. Canaries are good singers, constantly chirping and warbling. They were transported underground in a small wire cage (of various designs depending upon the area of the country or even pit by pit) by a Ventilation Officer or Safety Officer or Rescue Man. When gas was present they would detect the smallest amount as their hearbeart is 100 times faster than ours and would absorb the gas quicker into the bloodstream, then they would stop singing and become agitated. They would drop off their perch in a small percentage of carbon monoxide gas giving men an indication of the gas and allowing them to retreat to a fresh air base. Generally the bird would recover when given a whiff of oxygen from a bottle kept for such a purpose. They were made redundant and replaced by an electronic ‘sniffer’ canary in February 1996.

Check or Motty - Brass tabs or motties with the miner's number. One motty given to the Banksman, who operated the signals, when you were getting into the cage to go underground and another when coming out of the pit. This served 2 purposes. No1 was for payment and No2 for safety, i.e. knowing who was underground and when they came out of the pit. When the 2 checks were on the peg, both could be seen at a glance because the first check was larger and the smaller one was on top. Generally at most collieries, to help differentiate, a round check or square one for example was given to the Banksman when going into the pit and an oblong one was kept by the person until returning to the surface. Many men had a clip on the battery where the check or 'mottie' was kept safely on their person until given back.
Check Viewer - A viewer employed by the leasor to see that the provisions of the lease are duly observed.
Check Weigher - Mottie or swipe card to register manpower underground and timekeeping.
The weigher employed by the workmen. The Coal Mines Regulation Act of 1877 gave the miners for the first time, the freedom to appoint checkweighers. It was a job given to a man who was literate and good at reckoning, usually a union man.
He was a man chosen by the miners union to check the weight of each tub of coal raised out of the mine on behalf of the workforce as against the amount registered by the person appointed by the Company. This was to make sure that the amount of coal sent out the pit would be paid for at the rate agreed in the contract and was not 'weighed light' as some unscrupulous companies did. Some companies made the miners produce coal at up to 3,000 pounds to the ton! Whereas there was 2,240 pounds to a ton. The company would argue that should the coal be wet it would weigh lighter when it had dried out. The weight for the empty tub would be deducted from the weight of the full tub giving the amount of coal. Note it was imperative that only coal was paid for and any dirt sent out was not. Prior to the National Coal Board from 1st January 1947 occasionally a tub was tipped over and examined and even if a small amount of dirt was found, that tub was confiscated.
My experience of the job was at Teversal Colliery in Nottinghamshire even into the late 1950s where coal was still worked on a contract system at each coal face until that face finished. The coal was undercut by machine, bored and fired and loaded onto a face conveyor by a collier using a shovel. The coal then transferred onto the gate conveyor and each tub was loaded from that conveyor at a loading point in that gate and then transported by rope haulage to the pit bottom and loaded onto the cage and wound up the shaft. Each tub would be marked by chalk giving the name or number of the stall or panel and 2 men, one for the men and one for the NCB sat in a cabin near to the top of the shaft and as each tub out of the cage rested on the weighing machine before going to the tippler and onto the screens where dirt was sorted from the coal these 2 men would independently register the amount in their designated book for each panel number and would compare and agree on the total produced at the shift end. When the modern coal cutting loading machines were introduced in the 1950s, such as the trepanner and Anderson shearer, both coal and dirt was loaded out into tubs or mine cars or skips and the job of checkweigher dispensed with.

Electric Lamps. – Many portable electric lamps have been made; one by Swan (see Fig. 370). The electricity is supplied from a secondary battery, and the lamp will burn all day, giving a light of about half a candle; it weighs about 6 pounds. None of the numerous varieties of portable electric safety-lamps are yet in general use. There are, however, a great many fixed incandescent lamps used underground. These lamps are essentially safetylamps, as the air is entirely excluded unless the lamp should be broken. If the lamp were broken in an explosive mixture it would cause an explosion, but this is an improbable contingency. These lamps are now used to a considerable extent for lighting the pit porches, underground engine-houses, and, in some cases, engine-planes for long distances underground. The only practical danger in their use arises, not from the lamp, but from the conductors which convey the current; should these be too near each other, the current might pass between them and set fire to the timber; or should there be an explosive mixture, and the wire was severed, there would be a spark at the moment of severance, which would cause an explosion. These dangers may be reduced to a minimum by covering the conductors thickly with insulating material, and placing the positive and negative conductors at opposite sides of the road whenever practicable. Where the lamps are placed "in parallel," only a low voltage can be used, say 100 volts, and there is not much danger of the insulation being destroyed. If, however, the lamps are placed "in series," then a very high voltage may be employed, with a proportionate increase of risks. (See also Arc Electric Lamp)

Goaf, gob or gobbing - is the void left behind the coal face after the coal has been extracted.
This is where subsidence starts when the strata above the void breaks and collapses and eventually the surface lowers. Methods to prevent severe subsidence have been tried....in modern times by power stowing dirt produced by ripping the access gates (roadways) to the coal face and packing the dirt tight into the void. However this method was only done when the dirt was easily crushed and able to be blown through pipes or pushed by mechanical means into the Goaf. The modern system is to let the Goaf collapse and by strategically planning the coal face areas leave pillars of support between panels (coal faces) to lessen the subsidence.
Strip packing was the previous system and that was where packs of gate strata were built at the side of the gate roads to the face and at distances throughout the face line behind the coal face such as 3 yards of pack or walling, then a 3 yards gap of Goaf void, then another pack, another void and so on from one access gate road to another.

Back in 1849, as part of his wages, which averaged 3s. 9d. to 4s. 3d. per day for 8 hours working, 4 or 5 days a week, he was given a house with two or three rooms, according to the number in his family, and a garden, also a fother (a cart-load) of small coals each fortnight, for which he paid sixpence.
1890s The hewer was the coal-digger. The seam he worked could be so low that he could hardly creep into it on hands and knees, or high enough for him to stand upright. He was the responsible workman who loosens the coal from the bed. The hewers were divided into "fore-shift" and "back-shift" men. The former usually worked from four in the morning till ten, and the latter from ten till four. Each man worked one week in the fore-shift and one week in the back-shift, alternately. Every man in the fore-shift marked "3" on his door. This was the sign for the "caller" to wake him at that hour. When roused by that important functionary he got up and dressed in his pit clothes, which consisted of a loose jacket, vest, and knee breeches, all made of thick white flannel; long stockings, strong shoes, and a close fitting, thick leather cap. He then took a piece of bread and water, or a cup of tea, but never a full meal. Many prefer to go to work fasting. He would take a tin bottle full of cold water or tea, a piece of bread, which was called his 'bait', his Davy lamp, and "baccy-box." At the pit he got into the cage, and was lowered to the bottom of the shaft, where he lit his lamp and proceeded "in by," to a previously arranged place to meet the deputy. This official examined each man's lamp, and, if found safe, returned it locked. Each man then found from the deputy that his place was right and proceeded onwards to his cavel (lot drawing or a lottery to decided the working-place of each individual). He then went to his place of work with his picks in one hand, and his lamp in the other. He would travel like this a distance varying from 100 to 600 yards. Sometimes the roof under which he had to pass was not more than three feet high. To progress in this space he kept his feet wide apart and his body bent at right angles to his hips. His head was held well down, and his face looked straight ahead. On arrival at his place of work he undressed and began by hewing out about fifteen inches of the lower part of the coal. He thus undermined it, and the process was called kirving. The same was done up the sides. This was called nicking. The coal thus hewn was called small coal, and that remaining between the kirve and the nicks was the jud or top, which was either displaced by driving in wedges, or was blasted down with gunpowder. It then became the roundy. The hewer filled his tubs, and continued thus alternately hewing and filling.

Hurrier, also sometimes called a Coal Drawer or Coal Thruster - was a child or woman employed by a collier to transport the coal that they had mined. Women would normally get the children to help them because of the difficulty of carrying the coal. Common particularly in the early 19th century, the hurrier pulled a corf (baskets or small wagons) full of coal along roadways as small as 16 inches in height. They would often work 12 hour shifts, making several runs down to the coal face and back to the surface again. Some children came from the workhouses and were apprenticed to the colliers. Adults could not easily do the job because of the size of the roadways, which were limited on the grounds of cost and structural integrity. Hurriers were equipped with a "gurl" belt – a leather belt with a swivel chain linked to the corf. They were also given candles as it was too expensive to light the whole mine.

Stonedust - Crushed limestone (calcium carbonate). The ignition of naturally occurring methane gas is serious enough, but if this propagated a coal dust explosion then the consequences could be devastating throughout the mine. To help reduce the risk of this happening stone dust was introduced, the idea being that it would provide a concentration of suspended dust particles in the path of the flame of an explosion, it was hoped that this would reduce temperatures and arrest an explosion. Stone dusting became compulsory on the 1st January 1921.
Stonedust barriers - (see stonedust above)....a number of loose boards erected on platforms supported across a roadway above head height. Loose stonedust was piled on top of the boards. A specific number of shelves containing stonedust were erected in the main gate of the panel. Certain distances were laid down. A light barrier was to be maintained within say 130m of the coal face and a heavy barrier containing more shelves say up to 250m from the face. A new system using hanging bags of water (nicknamed bats) from supports has replaced some of the barriers. Should an explosion arise the idea was that the shock wave would knock the barriers down upset the shelves and the stonedust would blanket the roadway thereby cutting off flames from the explosion.
