摘要
雄山煤矿长期存在生产接替紧张、煤炭资源采出率低的难题;留设小煤柱开采是提高煤炭回收率、实现资源绿色开采有效途径之一;依据15^(#)煤层工作面地质条件,理论计算小煤柱宽度合理范围在7.34~8.61,模拟分析煤柱留设合理宽度为10 m(±0.5 m);应用留设区段小煤柱技术后矿井获得了良好的经济效益。
Aiming at the problems of tight production succession and low coal resource recovery rate in Xiongshan Colliery,the paper proposes setting small coal pillar mining to improve coal recovery and realize green mining of resources,theoretically calculates the reasonable width of small coal pillar to be 7.34 ~8.61 according to the geological conditions of No.15 coal seam working face,simulates and analyzes the reasonable width of coal pillar to be 10 m(± 0.5 m),whose application achieves good economic benefits.
