高应力大断面煤巷支护技术研究

基于煤矿开采规模和强度的增大、地质条件日益复杂、地应力随之增高、煤巷支护施工存在困难，围岩松软条件下煤巷支护的问题，对高应力大断面煤巷支护技术进行了研究，掌握巷道的环境条件和相关参数，提高支护结构的稳定性与耐用性，以此控制巷道变形和损坏，促进煤矿开采工作安全、可靠、高效开展。

Large Section under High Stress Roadway Supporting Technology Research

Based on the scale and intensity with the increase of coal mining and complex geological condition, in-situ stress also increased, subsequently brought difficulties for supporting in coal roadway, the soft surrounding rock under the condition of coal roadway supporting problem was particularly prominent, therefore, large section of high stress coal roadway supporting technology were studied, roadway environment conditions and related parameters were mastered to improve the stability of the supporting structure and durability, control the roadway deformation and damage and keep coal mining working safe, reliable and efficient.
