摘要
滑放工艺在大倾角工作面通过调整倾斜,既符合《煤矿安全规程》之规定,又减少了成本的投入,符合高产高效工作面的要求。同时,通过工作面的缩面开采,减少了煤柱损失,提高了煤炭资源回收率,并创造了可观的经济效益。
Adjustment of gradient in large dip angle working face not only corresponds with ＂Coal Mine Safety Regulations＂ regulations,reduces the cost of inputs,but also satisfies the need for high production and efficiency working face.By reduction in area mining in working face,coal pillar damage is reduced and the recycling rate of coal resources is improved,which creates considerable economic benefits.
