摘要
通过对倾角45°左右,厚煤层走向长壁综放开采支护系统稳定性的理论分析,提出了临界倾倒角的概念并建立了相关的数学模型。在实践基础上总结出了动态、静态情况下有效控制工作面支护系统失稳的开采技术及管理经验。
According to analysing the theory of longwall caving support system stability,this paper puts forward the ancept of critical angle and establishes the relevant maths models,and sums up the mining teshnical and management experrience of support system stability under dynamic,static circumstance posed on proutice.
