摘要
15101工作面回采时通过煤层大倾角段。根据以往的经验,采取了一定的防滑防倒措施,但是并未达到预期开采效果。在考察其他煤矿综采工作面过大倾角段措施的基础上,结合工作面实际情况,对现有的大倾角回采措施进行了优化。现场实践结果表明,优化后综采工作面能保持预定的回采速度,实现大倾角条件下煤层的安全开采。所述内容可为大倾角综采工作面的回采提供一定的参考。
The 15101 working face passed through the large dip section of the coal seam during mining.According to previous experience,certain anti-skid and anti-fall measures have been taken,but the expected mining effect has not been achieved.On the basis of investigating the measures of fully mechanized mining faces of other coal mines with large dip angle,combined with the actual situation of the working face,the existing mining measures with large dip angle were optimized.The field practice results show that after optimization,the fully mechanized mining face can maintain the predetermined mining speed and realize the safe mining of coal seams under the condition of large dip angle.It can provide a certain reference for the mining of fully mechanized mining face with large dip angle.
