煤矿开采沉陷的部分充填开采技术

Partial filling mining technology for coal mining subsidence

虽然煤矿开采提高了经济效益,但也引发了诸多环境问题,采空区沉陷便是其中之一。大量充填开采项目的展开,原固废变成材料,将导致充填材料价格上涨,在充填开采较为普遍的山东地区已开始逐步影响到矿井生产。为控制成本,减轻环境影响,部分填充开采技术在煤矿开采沉陷填充中得以广泛应用。针对被保护物的保护等级,在保护等级较低的开采范围采用部分充填技术,可以有效的处理固体废弃物,又能有效的降低充填成本。

Although coal mining has improved economic benefits, it has also caused many environmental problems, and the subsidence of goaf is one of them. The expansion of a large number of filling mining projects and the transformation of raw solid waste into materials will lead to a rise in the price of filling materials. In Shandong, where filling mining is more common, it has begun to gradually affect mine production. In order to control the cost and reduce the environmental impact, partial filling mining technology has been widely used in coal mining subsidence filling. According to the protection level of the protected object, the partial filling technology is adopted in the mining area with low protection level, which can not only effectively treat solid waste, but also effectively reduce the filling cost.
