摘　　要： 针对木城涧煤矿急倾斜厚煤层短壁开采特殊地质和技术条件,通过调研和现场实测,并应用理论分析、数值计算,系统地探讨了急倾斜厚煤层短壁综采工作面的矿压显现规律,确定了合理的支架工作阻力及超前支护距离,并对现场应用效果进行分析。 According to the special geological and technical conditions of the shortwall mining in the steep inclined thick seam of Muchengjian Mine,with the investigation and site measurement,the theoretical analysis and numerical calculation was applied to systematically discuss the mine strata pressure behavior law of the shortwall mining in steep inclined thick seam and to set the rational work resistance of the powered support and the pilot support pressure.The site applied effect was analyzed.
