复杂地质软高突出煤层超前掘进留煤加固与防突技术应用

Application of Retaining Coal Reinforcement and Outburst Prevention Technology in Advance Excavation of Soft and High Outburst Coal Seam in Complex Geology

通过对软煤层构建耦合动力模型,使用COMSOL对其进行仿真训练,提出在复杂地质环境下,掘进留煤层开采时的加固与防突技术方案,有效提升开采效率和开采的性价比。

By constructing the coupling dynamic model of soft coal seam and using COMSOL for simulation training,this paper puts forward the reinforcement and outburst prevention technical scheme when excavating the reserved coal seam in complex geological environment, so as to effectively improve the mining efficiency and cost performance of mining.
