摘要
厚煤层工作面的开采引起的采动应力更为复杂,为保证工作面安全开采,必须计算支架合理的支护强度。拟采用理论分析和数值模拟相结合的方法对支架的支护强度进行研究,通过经验估算法得到工作面液压支架支护强度为1.008 MPa,通过数值模拟得到采场支架的支护强度大约为1 MPa,最后认为液压支架合理的支护强度为1 MPa。
The mining stress caused by the mining of thick coal seam is more complex. In order to ensure the safe mining of the working face, the reasonable supporting strength of the support must be calculated.This paper adopt the method of combining theoretical analysis and numerical simulation on the supporting strength of the working face hydraulic support,and proposed that the supporting strength of the working face hydraulic support is about 1.008 MPa through empirical estimation method, concluded that the rational supporting strength of hydraulic support is1 MPa.
