摘　　要：厚硬煤层开采一直是煤炭行业面临的技术难题之一。传统的开采方式往往导致煤体破碎不充分、放煤效率低下,从而严重影响煤炭资源的回收率。为解决这一问题,文章深入探讨厚硬煤层综放开采中的预裂技术,特别是水压致裂技术的应用。通过深入分析水压致裂技术对顶煤强度的影响,旨在为厚硬煤层开采提供新的技术思路,优化开采流程,提高煤炭生产效率,为煤炭行业可持续发展作出贡献。The mining of thick and hard coal seam has always been one of the technical difficulties faced by the coal industry.The traditional mining method often leads to insufficient coal body crushing and low coal caving efficiency,which seriously affects the recovery rate of coal resources.In order to solve this problem,this paper deeply discusses the pre-splitting technology in fully mechanized caving mining of thick and hard coal seam,especially the application of hydraulic fracturing technology.Through in-depth analysis of the influence of hydraulic fracturing technology on top coal strength,it aims to provide new technical ideas for the mining of thick and hard coal seams,optimize the mining process,improve coal production efficiency,and contribute to the sustainable development of the coal industry.
