摘　　要：介绍了急倾斜煤层开采的现状,通过分析急倾斜煤层中可能出现的瓦斯问题、急倾斜煤层开采后岩层的移动以及急倾斜煤层开采分析等问题,论证了煤层的开采是一个综合性较强、影响和制约因素很多的复杂系统。开采急倾斜特厚煤层时利用高效安全的机械化采煤方法,在煤层厚度较大的情况下,可以实现开采方法工效高、工艺简单、掘进巷道少、吨煤费用低等优点。Introduces the present situation of inclined coal seam mining,according to the analysis about the inclined coal seam gas emission,the overlying strata movement after mining and the mining analysis of the inclined coal seam,arguing for that the coal mining is a complex system,has many influence and restriction factors.The inclined coal seam mining with the mechanization of efficiency and security,especially the thick coal seam,it can realize using the simple mining methods,high efficiency,and it can cut down the drifting,lower cost and so on.
