AB  - This data set obtains the dynamic evolution characteristics of surface subsidence parameters during mining through the measured data of surface deformation observation stations of three adjacent working faces of nalinhe No. 2 mine, Ordos City, Inner Mongolia Autonomous Region, simulates the cooperative change of rock and soil stress and strain and the law of surface subsidence during mining, and puts forward the optimization scheme of soil vegetation zoning monitoring based on the dynamic parameters of surface subsidenceIn order to obtain relatively complete calculation parameters of surface movement, master the law of surface movement in the mining area, and process the observation data of mining surface movement in working faces 31101 and 31102, so as to provide technical basis for the "three down" coal mining design of the mine in the future. The 31101 fully mechanized mining face of nalinhe No. 2 coal mine is located near the boundary of the mine field in the Middle East of the first mining area, with a face length of 241m, a strike length of 2600m, a minable area of 626600m2, a design mining height of 5.5m and a minable reserve of 4.49 million tons; 31102 fully mechanized mining face has a face length of 241m, a strike length of 3100m, a recoverable area of 746618m2, a design mining height of 5.5m and a recoverable reserve of 5.23 million tons. Ground elevation: + 1138 ~ + 1125.1m; Elevation of coal seam roof: + 571.898 ~ + 585.136m. When the coal seam becomes thinner, it shall be mined along the top and bottom according to the actual situation The data set includes 34 * 5 data of 31101 working face trend survey line; 20 * 5 data of 31101 working face tendency survey line; 31102 working face has 14 * 5 data of dip survey line, and the data set is completely open and shared.
