榆树田煤矿巷旁充填沿空留巷支护方式及参数选择

Support method and parameter selection for roadside packing gob-sideentry retaining in Yushutian Coal Mine

榆树田煤矿110403工作面运输巷采用超高水填充材料进行巷旁充填沿空留巷支护,根据生产条件和巷道支护状况,确定了巷旁充填体的布设及尺寸,提出充填体和留巷巷道加强支护的方法措施,选择了支护参数。通过数值模拟,预计了围岩变形量,可为该运输巷进行巷旁充填沿空留巷提供技术支持。

This article introduced the technology of using ultra-high water filling material to fill the roadway side and gob-side entry retaining support in the No.110403 working face of Yushutian Coal Mine.Based on production conditions and roadway support conditions,the layout and size of the roadway side filling body were determined,and methods and measures for strengthening support of the filling body and retaining roadway were proposed.Support parameters were selected,and the deformation of the surrounding rock was predicted through numerical simulation,which has provided technical support for roadside packing and gob-side entry retaining for the transportation roadway.
