【摘要】 以甘肃靖远王家山矿为例,通过相似模拟实验、现场矿压观测和工业性试验等手段,综合分析研究了大倾角煤层地质条件下,放顶煤综合机械化长壁开采矿压显现的复杂性,并进一步分析矿压显现的复杂性对支护系统、采煤工艺、放煤工艺的影响,最后提出改进措施及建议。
【Abstract】 Take example for Wangjiashan colliery,by the means of simulation,observation in situ and industrial examination,the complex of strata behavior in top-coal caving working face is analyzed in the condition of deeply inclined coal bed.The effect on technology of strata behavior is analyzed.Finally,the advice is given.
