摘要
根据较薄煤层短壁机械化开采工艺,分析了回采过程中薄煤层行走支架与围岩作用关系,采用辅助面积理论确定了薄煤层行走支架的工作阻力。通过三维数值模拟研究对薄煤层行走支架的支护强度进行了校核,为薄煤层行走支架的结构设计提供了可靠参数。
According to short-wall mechanical mine technics, interactional relation between rocks and crawler-type mobile roof support is analyzed. The method of theoretic calculation is introduced to design the shoring resistance of crawler-type mobile roof support. Through 3D numerical simulation,the shoring intensity is proof-tested, and proves that it＇s reliable parameter for framework design of crawler-type mobile roof support..
