厚煤层大采高开采端面稳定性分析

Stability Analysis for Large Mining Height Mining End-face in Thick Seam

  • 摘要: 为了对厚煤层大采高端面稳定性有个正确的认识,采用理论分析和数值模拟方法,对厚煤层大采高开采端面稳定进行研究,得出支架工作阻力、煤岩体的力学性质、煤层倾角是端面稳定的主要影响因素。同时提出控制端面稳定的相应措施,通过顶板注浆,提高顶板的强度、适当提高支护阻力是防止端面冒落的有效措施。
    Abstract: In order to have a correct understanding for end-face stability of thick coal seam height mining, we used theoretical analysis and numerical simulation method to study the end-face stability of thick seam with large mining height mining. The results show that working resistance of support, mechanical properties of coal rock and the angle of coal seam are the major influence factors of end-face stability. Corresponding measures to control the end-face stability are proposed to prevent the falling of end-face stability including roof grouting, improving roof strength, and improving support resistance.
