Variable mining width coordinated mining method, module, storage medium and system

Abstract

The invention provides a variable mining width coordinated mining method, a module, a storage medium and system. The variable mining width coordinated mining method comprises the steps that allowablemining deformation of the surface of a mining area is acquired; the mining condition value of the mining area is acquired; observed data of the mining area are acquired; the observed data include at least a surface subsidence coefficient, a tangent value of a main influence angle and coal seam dip angle and horizontal movement coefficients; a relationship curve between a surface subsidence rate and a mining width-depth ratio is obtained; the maximum width of a skip-milling face and the minimum width of a milling face are calculated according to the maximum allowable slope of the surface, mining depth, the surface subsidence coefficient, the tangent value of the main influence angle and the horizontal movement coefficient; and the width of the skip-milling face and the width of milling faceadopted in actual variable mining width coordinated mining are determined according to the maximum width of the skip-milling face and the minimum width of the milling face. According to the variablemining width coordinated mining method, the module, the storage medium and system, the problem that the deformation is gradually increased due to the fact that the surface is affected by repeated mining of adjacent working faces by using same working face size to mill in the prior art is solved.

Description

technical field [0001] The invention relates to the field of coal mines, in particular to a variable mining width coordinated mining method, module, storage medium and system. Background technique [0002] Ecological protection is one of the core issues considered in mining design, and the damage to the environment caused by coal mining is mainly reflected in the subsidence and deformation of the ground surface. Excessive subsidence of the surface may cause large-scale water accumulation on the surface in mining areas with high phreatic water levels; excessive deformation may cause discontinuous deformation such as cracks on the surface, causing damage or loss of vegetation, soil water content and mineral content. [0003] In the process of production, people noticed that the surface ecology has a certain self-repair ability, that is, after a certain degree of ecological damage caused by mining, the surface vegetation can recover naturally in a short period of time without c...
