摘　　要：针对某煤矿工作面急倾斜煤层分段开采矿压冲击的问题,研究与分析了分段开采时上覆岩的垮落特点、分段开采的冲击机理,提出了利用防控动载、静载力源的卸压防治技术预防矿压灾害的方案,通过煤层顶板深孔爆破实现动载防控,底板钻孔爆破实现静载防控。在某工作面实施该矿压防控方案,结果表明,实施矿压防控措施后,开采作业中矿震发生的次数以及总能量均逐渐减少,矿压防控效果良好。In response to the problem of mining pressure impact during segmented mining of steeply inclined coal seams in a certain coal mine,this paper studies and analyzes the collapse characteristics of the overlying rock during segmented mining,the impact mechanism of segmented mining,and proposes a plan to prevent mining pressure disasters by using pressure relief prevention and control technology for dynamic and static load sources.Dynamic load prevention and control are achieved through deep hole blasting of the coal seam roof,and static load prevention and control are achieved through drilling and blasting of the bottom plate.The implementation of the mine pressure prevention and control plan in a certain working face showed that after implementing the mine pressure prevention and control measures,the number of mine tremors and total energy during mining operations gradually decreased,and the mine pressure prevention and control effect was good.
