摘　　要：无煤柱开采是提升矿井采掘效率,提高煤炭资源回收率的重要途径。以高河矿W1319工作面巷道布置为例,提出了留大煤柱护巷、传统无煤柱护巷、工作面过空巷新型无煤柱护巷3种巷道布置方式,通过现场调研、数值模拟分析和工程实践论证了基于工作面过空巷布置方式的无煤柱开采技术的可行性。Pillarless mining method is an important way to increase production efficiency of coal mine and recovery rate of coal resources.On the basis of the roadway layout of W1319 working face of Gaohe Coal Mine,three roadway layout modes were proposed,i.e.retaining large coal pillar for roadway protection,tranditional pillarless roadway protection,new pillarless roadway protection based on working face passing through empty roadway.The feasibility of the new pillarless mining method based on working face passing through empty roadway was demonstrated by field investigation,numerical simulation analysis and engineering practice.
