【摘要】 针对攀枝花煤业集团花山煤矿21141综采工作面大倾角、复合顶板、地质构造复杂的特殊条件及该条件下综合机械化开采过程中遇到的片帮冒顶及回采推进困难的问题,采用数值模拟方法研究了该条件下影响片帮冒顶发生的因素,并在现场进行了治理实践,取得了良好效果,为该工作面条件下综合机械化开采的推广提供了成功经验。更多还原

【Abstract】 This paper studied the influence factors of roof and coal-wall breakage by the means of the computer simulation under the condition of large slope,complex roof and geological structure that are occurred in No.21141 fully-mechanized face.Some difficulty,including roof and coal-wall breakage and slow caving velocity,occurs during the production of No.21141 face.In addition,these difficulties are solved and the successful experience is gained about fully-mechanized mining method applied on similar coal-face.更多还原
