摘要
为了探索爆破切顶卸压沿空留巷开采技术在提升煤矿开采效率及安全方面的有效性,对该技术的实际应用情况进行了研究。基于巷旁支护设计、爆破施工与喷浆防护策略,对沿空留巷开采效果进行了全面评估,详细探讨了爆破切顶卸压技术在实际应用中的关键参数,以及其对开采效率和矿山安全方面的影响。研究结果表明,该技术可以有效提升煤炭的采出率,降低了事故发生率,同时显著提高了巷道的稳定性。
In order to explore the effectiveness of the blasting roof-cutting pressure relief technology in improving the efficiency and safety of coal mining,the practical application of the technology was studied.Based on roadway side support design,blasting construction and shotcrete protection strategy,the mining effect of gob side entry retaining was comprehensively evaluated,and the key parameters of blasting roof-cutting pressure relief technology in practical application were discussed in detail,as well as its influence on mining efficiency and mine safety.The research results show that the technology can effectively improve the coal recovery rate,reduce the accident rate,and significantly improve the stability of the roadway.
