Comprehensive Treatment Mode of Mining Subsidence Area Based on Whole Life Cycle

According to incomplete statistics, the coal mining subsidence area in China has reached 2 × 108 hm2. There are many ecological environmental problems in the coal mining subsidence area, such as geological disasters, land resource destruction, and water environment destruction, which restrict the green and healthy development of economic society. The current work through different geological conditions and the ecological environment problems caused by mining under natural environment comprehensive analysis, according to the climate, vegetation, mining methods, and mining conditions, raised the six kinds of coal mining subsidence area ecological environment problems mode of eastern Inner Mongolia, North-west, Qinghai, the Northeast, North China, Southwest model. We comprehensively analyzes the main problems of six modes of ecological environment problems in mining subsidence areas and puts forward the corresponding treatment technology scheme based on the concept of the whole life cycle. Based on the model of ecological environment problem, main treatment object, and treatment technology, the comprehensive treatment model is divided into the eastern Inner Mongolia model, Northwest model, Northeast model, North China model, Southwest model and Southeast model.
