摘要
工作面顶板结构模型是回采工作面上覆岩层运动规律的直观量化表现,根据工作面顶板结构模型,可以对液压支架的支护强度进行计算,从而确定液压支架的工作阻力。该文根据某矿工作面地质条件,在确定该工作面顶板结构模型的基础上计算了液压支架的支护强度为P＇T=1.62~1.69MPa。
The working face roof structure model is the intuitive and quantitative performance of working face overburden movement law, according to the working face roof structure model, calculated the supporting intensity of hydraulic support, then determined the working resistance of hydraulic support. According to geological conditions of a mine working face, based on determining the model of the working face roof structure, calculated the supporting intensity of hydraulic support that is P＇T=1.62~1.69 MPa.
