摘　　要：放顶煤技术是适用于较厚煤层开采的一种采煤方法,采用滑移支架放顶煤开采替代π型钢梁与单体液压支架配套支护放顶煤开采,有效解决了支护不及时、支护稳定性差、工艺复杂和工人劳动强度大的问题,而且不等长工作面具有安装、回撤架子既方便又不减产等优势。The caving technique is fit for thick seam mining.The sliding support caving mining replaces the roof coal caving with π steel beam and single hydraulic support matching coal caving,some problems are effectively solved,such as support not timely,support poor stability,process complexity and big labor intensity.The face of unegual length has both convenient and not cut advantages in support installing and retracement.
