四川省采煤沉陷区分级标准探讨

Discussion on classification standard of coal mining subsidence area in Sichuan Province

针对四川省采煤沉陷区损毁特征及损毁程度,采用矿山地质环境影响评估分级方法,从采煤沉陷区重要程度、采煤沉陷区损毁面积及程度、采煤沉陷区地质环境条件复杂程度3个方面,对四川省采煤沉陷区分级标准进行了有益的探索,为四川省采煤沉陷区综合治理工程的科学规划、精准施策作了一些基础工作。但是,其中一些量化指标还需要根据四川省采煤沉陷区实际情况进行调整。

Aiming at the damage characteristics and extent of coal mining subsidence areas in Sichuan Province,the mining geological environmental impact assessment classification method was adopted,from the importance of coal mining subsidence area,the damage area and extent of coal mining subsidence area and the degree of complexity of geological environment conditions in coal mining subsidence area.On the one hand,beneficial explorations had been made on the classification standards for coal mining subsidence areas in Sichuan Province,and some basic work had been done for the scientific planning and precise policy implementation of comprehensive treatment projects for coal mining subsidence areas in Sichuan Province.However,some of these quantitative indicators needed to be adjusted according to the actual conditions of coal mining subsidence areas in Sichuan Province.
