摘要
大同煤矿集团公司晋华宫矿南山区域402盘区12#层为侏罗系厚煤层赋存区。通过对该区域的地质情况、开采矿压总结分析,初步对支架的架型、工作阻力进行设计研究,实现了"两硬"条件下6 m厚煤层一次采全高综采工作面的安全高效生产,创造了可观的经济效益。
The 12# layer 402 panel is the occurrence al Jinhuagong Mine of Datong Coal Mine Group. By analysing the regional geologic status and mining pressure, the type and working resistance of support are preliminarily designed, the safe and efficient production of mining overall height of fully mechanized working face with 6m thick coal seam under the ＂ two hard＂ conditions is realized, the considerable economic benefit is created.
