以山西肖家洼煤矿实际地质条件为工程背景,针对13号煤层221302工作面材料顺槽受上覆8号煤层和相邻13号煤层工作面回采空间交叉强动压显现问题,通过分析上下煤层同采动压影响机理和上下煤层群围岩变形破坏规律,提出留窄煤柱沿空掘巷及水力压裂切顶卸压护巷协同治理技术,保证13号煤层综放工作面安全快速推进,确保矿井实现高产高效的生产目标.
Research on Collaborative Treatment Technology for Energy Release of Surrounding Rock in Tunnels Affected by Spatial Cross Dynamic Pressure
Taking the actual geological conditions of Xiaojiawa Coal Mine in Shanxi Province as the engineering background,aiming at the cross-strong dynamic pressure development of the working face of 221302 coal seam in 13# coal seam by the overlying 8# coal seam and the mining face of adjacent 13# coal seam,by analyzing the influence mechanism of the co-mining dynamic pressure of the upper and lower coal seams and the deformation and failure law of surrounding rock,this paper puts forward the joint management technology of cutting the narrow coal pillar along the gob and protecting the roadway by hydraulic fracturing to ensure the safe and rapid advance of the 13# coal seam caving face and ensure the high yield and high efficiency of the mine.
