摘要
根据袁店一井煤矿的地质概况,采用临时支护和永久支护相结合的方法来控制掘进期间和掘进后巷道的变形,并通过布置测点观测及时调整和优化支护参数,以达到最优的支护效果,减少材料消耗,降低成本,保证矿井的安全生产。
Based on the geology of Yuandian No.1 Coal Mine,the methods of temporary supporting and permanent supporting were used to control the deform during and after excavation.By using the data of observation from measuring points,the supporting parameters were adjusted and optimized to achieve optimal supporting effect,so as to reduce material consumption and costs,and ensure the safe production of coal mine.
