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。
In recent years, with the rapid development of science and technology, new polymer materials have been widely used in coal mines. With the increase of mining depth in most domestic production mines, the pressure in roadways has been significantly increased, especially in fully mechanized coal mining face. Before and after the cycle pressure , A large number of film gangs have emerged and their roofs have been hitched. This has seriously hindered the output and posed a severe test on safety in production. Chemical reinforcement material in the coal after reasonable filling, can effectively improve the hardness of the coal wall, effectively control the sheet to help the roof accidents, in order to balance, formal, safe production to provide effective protection.
