【摘要】：针对资源整合兼并小矿井中小窑破坏区残留煤柱的突出难采问题,以赵屋煤矿15号煤为工程背景,首次提出了连续采煤机短壁复采方法,介绍了短壁巷道布置方法、高效装备、掘采工艺、通风方式、巷道支护与顶板控制等方面的应用情况。现场实践表明,连续采煤机短壁复采技术的巷道布置灵活性、设备安全高效性、顶板控制有利性等优势,较好地克服了小窑区残留煤柱分布繁杂无序带来的开采难题,有效减少了赵屋煤矿优质资源浪费,提高了资源采出率,解决了矿井服务年限急剧缩短、可持续发展受阻等生存问题,该技术的成功应用也为其他兼并矿井小窑区复采提供了宝贵的现场经验和技术解决途径。
[Abstract]:In view of the outburst and difficulty of mining residual coal pillar in small and medium kiln destruction area of small mine, taking No. 15 coal mine in Zhaowu Coal Mine as the engineering background, the short-wall remining method of continuous shearer is put forward for the first time, and the layout method and efficient equipment of short-wall roadway are introduced. Mining technology, ventilation, roadway support and roof control applications. The field practice shows that the advantages of roadway layout flexibility, equipment safety and efficiency, and roof control advantages of short-wall remining technology of continuous shearer have overcome the mining problems caused by the complicated and disordered distribution of residual coal pillars in small kiln areas. It effectively reduces the waste of high quality resources in Zhaowu Coal Mine, improves the recovery rate of resources, and solves the problems of survival such as the sharp shortening of mine service life and the hindrance of sustainable development. The successful application of this technology also provides valuable field experience and technical solution for the remining of small kiln areas in other annexed mines.
