摘要
初撑力在煤矿工作面液压支架参数中具有重要的地位,其对顶板控制的重要性已得到普遍认同。通过直接顶与老顶之间关系,建立叠合超静定梁的离层力学模型,求解液压支架的最佳初撑力范围,指导煤矿实际生产,可以减少顶板离层,增加顶板的稳定性,同时减少了支护成本,提高了采矿工作面的安全性。
Setting pressure in parameters of hydraulic support of coal mining face has an important role,it~ ira- portant position of the roof control has been accepted. Using the relationship between direct roof and main roof,buil- ded roof separation mechanical model of composite beams, solved the best range of setting pressure of hydraulic sup- port ,guided coal production, could reduce roof separation, increase the stability of roof, at the same time decrease costs and improve the security of the coal mining face.
