“凝固力”FSS化学加固材料在松软煤体仰采工作面的应用

近年来,随着科学技术的迅猛发展,新型高分子材料在煤矿得到广泛应用,国内大部分生产矿井随着采深加大,巷道压力明显提高,尤其是综采工作面,在周期来压前后,出现大量片帮、冒顶,严重制约产量,并对安全生产提出严峻考验。化学加固材料在煤体合理加注后,可以有效提高煤壁硬度,有效控制片帮、冒顶事故,为均衡、正规、安全生产提供有效保障。

Solidifies Strength FSS Chemistry Strengthen Materials and Admire the Application which Adopts the Working Range in the Soft Coal Body

In recent years,with the swift and violent development of science and technology,the new-type high polymer material is used widely in the colliery,domestic majority produces the mine with adopting strengthening deeply,the pressure of the tunnel obviously improves,especially adopt the working range comprehensivly,before and after cycle comes to press,helping a large number of scenes,roof fall,restrict the output seriously,and propose testing the safety in production severly.Chemistry strengthens materials af...
