综放工作面过陷落柱综合技术研究

Research on Comprehensive Technology of Overpassing Collapse Pillar in Fully Mechanized Caving Face

论文以同煤集团同生树儿里煤业为案例,研究综放工作面过陷落柱的综合技术方案。针对矿压规律研究、采动对陷落柱的活化分析、注浆加固技术、保护煤柱宽度和生产工序优化等关键技术提出了相应的内容和方法,形成了综放工作面过陷落柱的综合技术体系。该研究成果对我国同类型的工作面过陷落柱或其他地质构造具有很好的参考意义。

Taking Shuerli Coal Industry of Tongsheng Coal Group as an example,this paper studies the comprehensive technical scheme of fully mechanized caving face overpassing collapse pillar.Aiming at the key technologies such as the study of strata pressure law,activation analysis of subsidence pillar during mining,grouting reinforcement technology,protection of pillar width and optimization of production process,the corresponding contents and methods are put forward,and a comprehensive technical system for overpassing subsidence pillar in fully mechanized caving face is formed.The research results have a good reference significance for the same type of working face overpassing collapse pillars in China or other geological structures.
