摘　　要：在中厚煤层复合顶板切顶卸压无煤柱开采中,为保证留巷效果,通过深入研究岩性、锚索支护方式、切顶爆破参数、门架工作状态等关键参数,总结出中厚煤层复合顶板切顶卸压无煤柱开采最优施工参数方案,为类似条件下实施该技术提供了借鉴。In order to ensure the effect of retaining roadway, the optimum construction parameter scheme of compound roof cutting and pressure relief without coal pillar mining in medium-thick seam was summarized through in-depth study of key parameters such as lithology, bolt-cable supporting mode, roof cutting blasting parameters and gantry working state. All this can provide a reference for the application of this technology in similar conditions.
