Gangue self-cementing filling material for mine filling and application thereof
The invention discloses a gangue self-cementing filling material for mine filling and application of the gangue self-cementing filling material. The gangue self-cementing filling material is composed of gangue and water, wherein the mass percentage content of the gangue is 75-80%. The gangue adopted by the invention contains at least one of the following mineral components: illite, montmorillonite and kaolinit;, namely the gangue is one, two or three selected from illite, montmorillonite and kaolinite. The mass percentage of the mineral components of the material is not less than 20%; and the gangue needs to be crushed, the maximum particle size of the gangue does not exceed 20 mm, and the proportion of the gangue with the particle size of less than 0.3 mm is not less than 20%. The gangue self-cementing filling material disclosed by the invention does not need to be doped with a cementing material, so the cost of the filling material is greatly reduced, a low-cost way is provided for underground filling of gangue, popularization and application of a gangue filling technology are greatly promoted, and large-scale treatment and resource utilization of coal mine gangue solid wastes in China are assisted.
本发明公开了一种用于矿山充填的矸石自胶结充填材料及其应用。所述矸石自胶结充填材料，由矸石和水组成；矸石的质量百分含量为75～80％；本发明采用的矸石含有如下矿物成分：伊利石、蒙脱石和高岭石中至少一种，即可为伊利石、蒙脱石和高岭石中的一种、两种或三种；矿物成分的质量百分含量不低于20％，所述矸石需进行粉碎，矸石的最大粒径不超过20mm，其中，矸石的粒径小于0.3mm的比重为不低于20％。本发明矸石自胶结充填材料由于无需掺加胶结料，大幅降低了充填材料成本，为矸石井下充填提供了低成本途径，将大大促进矸石充填技术的推广和应用，助力我国煤矿矸石固废的规模化处理和资源化利用。
