摘　　要：在分析残采工作面煤柱留设尺寸受采空区、上覆岩层岩性、煤柱自身强度、采深、采厚、煤层倾角等采矿条件影响因素的基础上,探讨了残采煤柱工作面布置方式及支护技术。为类似条件下的工作面布置及支护提供经验。The coal pillar size of residual mining working face is affected by the gob, the overlying strata lithology, the coal pillar strength, the mining depth, the mining thickness, the dip angle of coal seam, and other mining conditions, Based on the analysis of the affecting factors, the support technology of residual coal pillar mining face layout and support were discussed in this paper. Provide experience for working face layout and support under similar conditions.
