摘要
为保证31201综放面回采过程中能够安全顺利的通过上覆22煤跳采煤柱区域,保证人员及设备安全,防止出现冒顶及支架压死等事故,研究制定了一系列安全措施。实施结果表明:该措施能够确保综放面顺利通过上覆煤层跳采煤柱应力集中区域,为类似工作面的开采工作提供了借鉴。
In order to ensure the safety of No. 31201 fully mechanized caving mining face passing through the overlying 22 seam skip-mining pillar area,to prevent the accidents of roof falling and support crushing,the safety measures were formulated. The results show that the measures can ensure the safety of fully mechanized caving face passing through overlying stress concentration area of skip-mining pillar and can provide reference for the mining of similar working faces.
