摘要：结合星村煤矿3302掘进工作面工程地质情况及组织管理水平，采用模棚综合评价法并按照三类危险源分类法，对影响深井巷道围岩稳定性的各种因素进行分类，建立了三类危险源影响因素模型。从事故发生原因及影响因素入手，识别出具有代表性的指标，合理构建了危险源风险评价的指标体系；从整体上对巷道围岩危险源的风险等级进行评价，最终得出巷道围岩危险源风险等级为危险；通过对图岩进行监测和优化巷道支护参数，进一步提高巷道围岩的稳定性。

Abstract: Combined with the engineering geologic conditions in 3302 heading face and the organization management level of Xingcun Coal Mine, various factors that influence the stability of the deep roadway surrounding rock were classified by using the fuzzy comprehensive evaluation method and according to the classification method of three types of hazards, and the influence factor model of three types of hazards was established. Starting from the causes and influence factors of the accidents, the typical index was identified and the index system for risk evaluation of hazards was reasonably built; an overall evaluation was made on the risk level of the roadway surrounding rock hazards, and it was finally concluded that the risk level of the roadway surrounding rock hazards was “dangerous"; through the monitoring of the roadway surrounding rock and the optimization of the roadway support parameters, the stability of the roadway surrounding rock was further improved.
Keywords: deep roadway; three types of hazard; analytic hierarchy process; fuzzy comprehensive evaluation
随着我国煤炭资源开采深度的增加，埋深超过于米的矿区和矿井不断涌现，深部巷道围岩所处地质环境逐渐复杂，自重应力增大、构造应力影响显著，高温高渗流等复杂环境给巷道稳定支护带来了巨大的困难[1-2]。星村煤矿位于山东省曲阜市，地面标高40m左右，煤层埋深为-900~-1300m，大埋深带来的高原岩应力使得星村煤矿成为典型的深部开采矿井。根据对巷道围岩稳定性危险源中的各因素进行分析，将这些因素作为星村煤矿巷道围岩危险源风险等级评价的指标因子，作出评价星村煤
