正常采煤工作面都是以走向长壁的形式布置,但是受地质条件变化的影响,煤层走向的方位有时也是变化的。乌海能源公司公乌素煤矿011604在布置工作面时就遇到了这样的问题。直线走向布置坡度增大,回采时将形成仰斜采煤,存在较大安全隐患,且降低煤炭的回收率,造成资源浪费。随走向布置,就形成了工作面的转角,在采至拐点处,增加了工作的难度。经研究,公乌素煤矿在011604工作面成功实施转采,并对控制前
The normal coal mining face is arranged in the form of longwall, but the orientation of the coal seam sometimes changes due to the change of geological conditions. Wuhai Wugu coal company 011604 energy in the layout of the face encountered such a problem. Straight line to the layout of the gradient increases, mining will be formed when the slope inclined coal mining, there is a big security risk, and reduce the recovery rate of coal, resulting in waste of resources. With the layout to the formation of the corner of the face, mining in the inflection point, an increase of the difficulty of work. After the study, Gong Wusi coal mine in 011604 face successfully transferred, and the control before
