摘　　要：针对中厚煤层开采后存在的矿压问题,文章选取A煤矿作为具体案例,运用数值模拟技术分析不同切顶高度对煤柱所承受的支撑压力的影响,并通过矿压监测进一步验证所提出的切顶支护参数的合理性。研究结果不仅为中厚煤层开采的围岩控制问题提供了有效的解决方案,还为类似条件下的工程实践提供了一定参考。Based on the problem of mine pressure after mining in medium-thick coal seam,this paper selects coal mine A as a specific case,uses numerical simulation technology to analyze the influence of different roof cutting heights on the support pressure of coal pillar,and further verifies the rationality of the proposed roof cutting support parameters through mine pressure monitoring.The research results not only provide effective solutions for the surrounding rock control problem in medium-thick coal seam mining,but also provide a certain reference for engineering practice under similar conditions.
