摘要:

本文针对王家岭煤矿20104综放工作面具体地质条件及开采现状,通过现场实测,对该工作面矿压显现规律进行了分析,结果表明:工作面初次来压呈现出分段来压现象,中部先来压且来压强度大,端部后来压且来压强度较小;工作面支架工作阻力主要分布在18.2~33.0MPa之间;来压期间,中部支架动载明显,中部部分支架工作阻力接近额定值,研究成果可为其他矿区综放工作面煤层开采提供依据。

Abstract:

This paper is study on the regularity of strata behavior in 20104 working face. According to the 20104 fully mechanized caving face’s specific geological and mining conditions of Wang Jialing coal mine take the method of field measurement. The results showed that the coal mining face would have a sectional pressurized phenomenon, central pressure strength and first-come, subsequently ends to pressure less intensity; the work resistance of working face mainly between 18.2 ~ 33.0MPa ; the middle bracket dynamic load significantly during the pressure, and the central part of the frame work resistance close to the rating, finally research can lay a foundation for the fully mechanized caving face mining in other mines.

Key words: thick coal seam, fully mechanized coal caving coal, strata behavior regularity, work resistance
