大倾角滑放工作面施工中技术难点的处理

Treatment of technique problems in the suspended support caving working face with large dip angle

大倾角滑放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。

The slide release process in big dip face by adjusting the tilt, consistent with ＆quot;Coal Mine Safety Regulations＆quot;provisions, but also reduce the cost of inputs, in line with the requirements of high yield and efifciency face. At the same time, through the face of the shrinking surface mining of coal pillars to reduce losses and improve the recovery rate of coal resources, and create considerable economic beneifts.
