双马煤矿小煤柱沿空掘巷技术探索与实践

Research and Practice of the Technology of Gob-side Entry Driving by Small Coal Pillars in Shuangma Coal Mine

国家能源集团宁夏煤业有限责任公司双马煤矿成功应用小煤柱沿空掘巷技术,不仅解决了传统大煤柱护巷造成的资源浪费、回采率低的产业现状问题,而且在很大程度上缓解了受采动压力影响造成的巷道长周期反复变形、生产接续失调问题,有利于矿井长期稳产、高产和可持续发展,产生了广泛的经济效益和社会效益。

The technology of gob-side entry driving by small coal pillars applied successfully in Shuangma Coal Mine of CHN Energy Ningxia Coal Industry Co.,Ltd.,not only solves the current industrial issues of resource waste and low recovery rate caused by traditional roadway protection by large coal pillars,but also greatly alleviates the problems of long-term repeated deformation and production continuity imbalance caused by mining pressure.This is conducive to the long-term stable production,high yield and sustainable development of mines and also has produced extensive economic and social benefits.
