斜沟煤矿厚煤层大采高开采探究

Study on the Greater Mining Height Mining of Thick Coal Seam in Xiegou Coal Mine

斜沟煤矿是国家"十一五"规划重点建设的10个千万吨级矿井之一,其主采煤层顶板属于复合型顶板,局部破碎严重,且回采过程中经常出现漏顶现象。结合斜沟煤矿开采中遇到的问题,分析了厚煤层大采高顶板运动规律,并探讨了工作面顶板控制措施,望对相关煤层开采提供借鉴。

Xiegou Coal Mine is one of 10 million-ton mines of national ＂Eleventh Five-Year Plan＂, and the main roofs in the coal seam belonged to composite roof, and local roof is seriously crushed and roof leakage phenomenon often occurs in the recovery process. Roof movement law of greater mining height mining in thick coal seam was analyzed, and control measures for roof were studied, which hopes to provide references for related coal mining.
