Design and Analysis of Bolt Supporting Scheme for Fully Mechanized Caving Face in No.2 Coal Mine of Yangquan Coal Industry Group

为解决80704综放工作面支护难度大、支护费用高等问题,提出了一种锚杆支护方案。在分析顶板支护、巷帮支护的基础上,对采用该支护方案后的巷道矿压、锚杆锚索载荷结果进行观测和分析。分析结果表明,该支护方案有助于解决现阶段锚杆支护技术所遇到的困难,为矿井的安全、高效生产提供有力的技术支撑,并且该研究成果在80704综放工作面工业新试验中取得了良好的技术经济效果。

In order to solve the problems of difficult support and high support cost of the 80704 fully mechanized caving face, a bolt support scheme was proposed. On the basis of analyzing the roof support and the roadway side support, this paper observed and analyzed the results of the roadway mine pressure and anchor cable load after applying the support scheme. The analysis results show that the support scheme can help solve the difficulties encountered in the current stage of bolt support technology, provide strong technical support for the safe and efficient production of mines, and the research results have achieved good technical and economic effects in the new industrial test of 80704 fully mechanized caving face.
