东部平原矿区矸石充填开采保护耕地研究

Research of Protecting Farmland By Backfilling With Gangue in Eastern Plains Mining Area of China

针对我国东部平原矿区,煤矿开采破坏耕地严重、煤矸石压占耕地数量大、"三下"压煤现象严重的情况,分析了矸石充填开采保护耕地的途径,研究了各种途径的可行性和保护耕地面积的模型。鉴于我国的国情,基于矸石量、耕地保护面积、置换呆滞资源量的协同关系,以建筑下采煤为切入点,提出了一种适合我国东部矿区的矸石充填开采保护耕地模式,并将研究成果应用于工程实例。

Aiming at the situations of coal mining badly damaged farmland,gangue covered farmland in large quantities and serious phenomenon of ＂three unders＂ pressed coal in the eastern plains mining area of our country.This paper analyzes the ways of protecting farmland by backfilling with gangue,and researches the feasibility of many ways and the models of protecting farmland area.In view of China’s national conditions,with mining under buildings as the breakthrough point,this paper proposed a model of protecting farmland by backfilling with gangue which is suitable for China’s national conditions on the base of collaborative relationship of gangue quantity,area of protected farmland and replacement of dull resources amount.Finally,the research is applied in engineering examples.
