青龙同昌15102工作面沿空留巷设计实践

Design Practice of the Along-Hollow Staying Lane at Qinglong Tongchang 15102 Working Face

为了提高15102工作面煤炭开采的回采率和回采量,采取沿空留巷实现无煤柱式开采,基于现场支护情况,提出工作面及沿空留巷具体支护方案,并进行支护强度计算。实际应用结果表明,采用优化设计后的沿空留巷开采,减少了煤柱使用率,有效提高了煤炭开采效率,值得进一步推广应用。

In order to improve the recovery rate and recovery volume of coal mining at the 15102 working face,a specific support scheme for the working face and along the air-holding lane was proposed and the support strength was calculated based on the on-site support situation.The results of practical application show that the optimized design of the coal pillar-free mining has reduced the use of coal pillars and effectively improved the efficiency of coal mining,which is worthy of further promotion and application.
