Study of coal pore characteristics and its effect on water injection

煤层注水是采煤工作面最基本最有效的防尘措施,如果注水措施采取得当的话,能降低采煤工作面的粉尘浓度,减少粉尘对采煤工人的危害,因而在国内外大多数煤矿都得到了广泛应用。本文笔者主要对煤的孔隙特性及其对煤层注水的影响做了简要探讨。

the coal seam water injection is the most fundamental and most effective dustproof measures of working face, if the injection measures properly, can reduce the coal mining working face dust concentration, reduce the harm of dust to coal mining workers, at home and abroad have been widely used in most coal mine.
