摘要
基为了回收安家岭矿北帮F23断层与姚吉坪陷落柱之间区域的煤炭资源,根据北帮开采现状、地质及煤层赋存情况,对该区域采用局部扩帮、陡帮开采方案的适用性进行了分析。对端帮压煤回收区域进行了多种方案的设计和对比分析,采用CEO-slope和FLAC软件进行了数值模拟,验证了各方案采动后的稳定性,并对工程量、采剥进度、运输系统、安全保障措施进行了分析和布置。研究结果表明,采用局部扩帮陡帮开采可回收煤炭资源132万t,创造经济效益11 600万元。
In order to recover the coal resources in the area between F23 fault and Yaojiping subsidence pillar in the north slope of Anjialing Mine, the article analyzes the applicability of the scheme of partial enlargement and steep slope mining in the area according to the mining present situation of north slope, geology and coal seam occurrence. The article carries out the design and comparative analysis of various schemes for end-wall coal recovery area. The numerical simulation is carried out by using CEO-slope and FLAC software, which verifies the stability of the schemes after mining. The article analyzes and arranges engineering quantity, mining progress, transportation system and security measures. The results show that 132,000 tons of coal resources can be recovered and 116,000,000 yuan of economic benefits can be created by mining with local expansion and steep slope.
