三软煤层大倾角俯采关键开采技术研究与应用

Research and Application of Key Mining Technology for Steep Dip Mining in Three Soft Coal Seam

谢桥煤矿在三软较薄厚煤层回收采区煤柱时,采用国内先进的大采高综采装备,布置大倾角俯采工作面,通过分析总结设备选型、顶板压力显现规律和工作面刮板输送机、液压支架、运输巷转载机、带式输送机等设备的防滑方法及回采技术管理,成功实现了三软煤层大倾角俯采工作面安全高产高效回采,达到了国内同类矿井先进水平,取得了良好的经济和社会效益。

In Xieqiao coal mine in three soft thick coal seam mining coal pillar recovery. Use domestic advanced fully mechanized mining equipment, arrangement of large inclined angle mining face. By analyzing the selection of equipment, roof pressure appear management rules and methods of anti-skid scraper conveyor, hydraulic support,transportation lane, loader belt conveyor equipment and mining technology. Successful implementation of the three soft seam with large inclined angle mining face of high yield and high efficiency mining safety. Has reached the domestic advanced level of the same mine, and achieved good economic and social benefits.
