为有效控制神东矿区大采高综采面煤壁片帮,结合神东矿区大采高综采面具体条件,通过理论分析和现场实测,分析了该矿区大采高综采面煤壁片帮机理及片帮影响因素。提出了注水软化煤层、来压快速推进、过断层固化破碎顶板、加强技术管理、保证端面距最小化和过上覆近距离煤层遗留煤柱矿压预测预报工作到位等防治煤壁片帮技术。现场实践表明,综合应用上述防治措施控制煤壁片帮效果良好。
In order to effectively control the coal mining sheet of the large mining height fully mechanized coal mining face in Shendong Mining Area and by combining with the specific conditions of the large mining height fully mechanized mining face in Shendong Mining Area and through theoretical analysis and field measurement, To help the mechanism and the film to help influence factors. Proposed water softening seam to push the rapid pressure to advance through the fault broken roof, and strengthen technical management to ensure that the face away from the minimum and the overlying coal seam pressure is close to the remaining coal pillar mine prediction and prevention work in place such as prevention and control technology. Field practice shows that the comprehensive application of the above control measures to control the coal wall to help a good effect.
