大倾角厚煤层综放工作面矿压显现规律实测研究

大倾角煤层易受剧烈地壳运动的影响,其煤层顶底板遭受破坏的程度比缓倾斜煤层要大。采用现场实测的研究方法,对大倾角厚煤层综放工作面矿压显现规律进行实测研究,为进一步理论分析提供实践资料,并为指导工作面支架选型及安全生产提供依据。

Study on the Field Measurement of the Mine Pressure Appearing Law of Fully Mechanized Mining Face in the Thick Seam with Large t Inclined Angle

The suffered damage of the roof and floor of the coal seam with large inclined angle is more serious than that of the gently inclined coal seam because the former is easily influenced by the vast movement of the earth's crust. Adopting the field measurement, this paper studies the mine pressure appearing law of fully mechanized mining face in the thick seam with large t inclined angle, which provides the practice materials for the further theoretical analysis, and provides some bases for the guidance of sup...
