    Abstract: A coal caving system (1) including a plurality of shields (3) with canopies (6) which are selectively operated to allow coal to cave onto a rear conveyor (37). In one aspect, the invention provides a shield control method including controlling the shield (3) to automatically open a door (6) associated with a rear canopy of the shield (3) responsive to a position of a shearer of the system.

    Abstract: A control system for controlling the elevation of a cutter of a longwall shearer in which the attitude of the body of the shearer and the rate of change of attitude with longitudinal movement of the shearer are monitored and the elevation of the cutter is varied as a function of the sum of the product of a first constant times attitude and the product of a second constant and the rate of change of attitude.

    Abstract: An auger machine, such as a mining machine, embodying features that reduce the cost of mining. The machine embodies jacks and skids which permit ready maneuverability of the machine adjacent the wall containing the seam to be mined, and has a cross conveyor for conducting away mined material from the auger string, which cross conveyor is located rearwardly of the front jacks and thus facilitates placing of auger sections in and removing auger sections from the string of augers used in mining by an efficient

    Abstract: A dividing cutting machine includes a cutter boom pivotable about a horizontal axis, at least one cutter head disposed on the cutter boom, a loader deck hingedly connected to the frame of the dividing cutting machine pivotable about a horizontal axis and provided with movable gathering arms for continuously sweeping the mined material upwardly over the loader deck to conveying means. Stops mounted on the cutter boom and on the loader deck at locations spaced from their respective horizontal pivot axes have a height which precludes physical contact between the cutter boom and the gathering arms in each mutual pivotal position.

    Abstract: Deep (long) parallel holes are drilled into a mine or tunnel face and explosive charges selectively exploded in some, but preferably not all, of such holes to fragment surrounding rock and join the holes. Methane migrates through the fractured formation to the hole which has not been exploded, or to a separately drilled drainage hole, and the unexploded or separate hole is first used to draw off explosive gases, where this is a problem. Then water is pumped through such hole or holes to saturate the formation to reduce dust suspension and also to cause additional gas migration. The fractured formation facilitates mechanical boring machines and reduces tool wear. The explosives are preferably provided at spaced intervals along a carrier tube with stiffeners to enable the tube to be pushed into the deep hole and with built-in electrical connections and stemming. The carrier for the explosives is preferably plastic and thus does not damage boring tools.

    Abstract translation: 在矿井或隧道表面钻出深(长)平行孔,爆炸物选择性地在一些但优选不是全部的这些孔中分解,以分解周围岩石并连接孔。 甲烷通过破裂地层迁移到尚未爆炸的孔中,或者通过另外钻出的排水孔进行迁移,首先将未爆炸或分离的孔用于抽出爆炸性气体,这是一个问题。 然后将水通过这样的孔或孔泵送以使地层饱和以减少灰尘悬浮并且还引起额外的气体迁移。 断裂的地层有助于机械镗床,并减少刀具磨损。 爆炸物优选地沿着具有加强件的承载管以间隔开的间隔设置,以使得管能够被推入深孔中并且具有内置的电连接和引导。 爆炸物的载体优选是塑料,因此不会损坏钻孔工具。
