煤巷全锚网支护参数的理论计算方法

Theoretical calculation method of bolt-mesh support parameters for coal roadway

应用理论计算和工程类比的方法,确定了不同煤厚条件下煤巷全锚网支护技术方案和支护参数,并在超化煤矿23051回风巷掘进工作面取得了良好的支护效果,为相似地质条件下煤巷掘进,合理确定支护参数,减少巷道围岩变形,实现安全生产提供了理论依据。

Using the methods of theoretical calculation and engineering analogy,the technical scheme and bolt-mesh support parameters of coal roadway under different coal thickness were determined,and the good support effect was obtained in the heading face of No.23051 return airway in Chaohua coal mine,which provides a theoretical basis for determining supporting parameters,reducing the deformation of the surrounding rock in coal roadway,and ensuring safety production under similar geological conditions.
