Quantitative Calculation Method Surface Subsidence Caused by Underground Mining Based on GIS
Abstract The mining subsidence basins are mostly irregular. The traditional method is difficult to achieve quantitative evaluation of mining subsidence damage. This paper investigated the quantitative indicators of land subsidence damage evaluation based on GIS. The calculation method of the area and volume of surface subsidence caused by underground mining was proposed. Firstly, the principle, requirements, methods and steps of drawing the sinking boundary line were given. A calculation method based on the subsidence area of the surface subsidence database was proposed. According to the sinking contour map, the calculation method of subsidence area based on the sinking contour map was proposed. Based on the calculation method of surface subsidence area and and the digital elevation model, the calculation method of the mining subsidence volume was put forward. The surface subsidence area and volume were calculated by numerical examples. This realized the quantitative evaluation of surface subsidence damage caused by underground coal mining, and promoted the application of GIS in mining damage assessment.
