摘　　要：针对河神庙矿千米矿井的高地应力、软岩的具体条件,进行了巷道支护方式与合理支护技术参数的研究。应用巷道支护理论预测方法,得出结论:河神庙矿巷道围岩为不稳定类型;巷道围岩最大预测变形量可达867.5mm,塑性破碎范围为5.9m;锚喷支护为巷道合理支护方式,给出了具体的技术参数。此研究成果为今后河神庙矿的规划设计和矿井建设施工提供科学可靠的工程决策依据。Under high stress and soft rock of km deep mine,development roadways＇supporting and its security control will become a key problem in the early development and construction.Therefore,it is necessary to study the roadway＇s reasonable supporting ways and their technical parameters according to special conditions of Heshenmiao coal mine.By the prediction methods of roadways＇supporting theory,outcomes are that 1） the development roadway＇s surrounding rock type is unstable,2） the predicted maximum deformation of roadways can reach to 867.5mm,3）bolt and shot-concrete support are the mast reasonable ways,and special supporting technical parameters were obtained.The research results will provide the scientific and reliable engineering decision-making basis for the planning design and mine construction of Heshenmiao coal mine in the future.
