Abstract

The invention relates to the technical field of coal mining, in particular to an earth surface subsidence control grouting filling system based on a separation layer distribution rule. The width of each transverse working area corresponding to the longitudinal depth of each working area at present and before the mine, the distribution depth of each separation zone, the rock expansion rate and the water content of each overlying stratum of the separation zone, and the corresponding total grouting filling amount under the longitudinal depth of the current working area are obtained; obtaining each Gaussian mixture model according to the width of each transverse working area and the distribution depth of each separation zone, and determining parameters of each Gaussian mixture model according to the distribution depth of each separation zone; and inputting each Gaussian mixture model parameter and the rock expansion rate and the water content of each overlying stratum of the separation zone into a grouting filling amount prediction network to obtain a corresponding grouting filling total amount prediction value under the longitudinal depth of the next working area, and further determining the grouting rate. According to the method, the total grouting filling amount can be accurately predicted, and the separation layer grouting filling effect is improved.

Description

technical field [0001] The invention relates to the technical field of coal mine mining, in particular to a surface subsidence control grouting filling system based on the distribution rule of the separation layer. Background technique [0002] With the advancement of my country's green mine construction, in order to realize environmental ecology and resource utilization efficiency, resource conservation and recycling are organically combined to form a virtuous circle of "resources-products-waste products-renewable resources". In order to avoid the subsidence of the overlying strata, a separation-layer grouting filling technology appeared to control the subsidence of the surface. The ground-distributed boreholes are filled into the separation-layer cavities formed inside the overlying rock during the rock movement process to fill the overlying rock with grinding slurry. The rock formation acts as a support, thereby reducing the rate of deformation of the overlying rock towar...
