Mining parameter optimization method, mining method, storage medium and computer equipment

Abstract

The invention provides a mining parameter optimization method, a mining method, a storage medium and computer equipment. The mining parameter optimization method comprises the steps that the ratio of the volume of the damaged rock mass to the volume of the overlying strata serves as the overlying strata damage ratio of the overlying strata; for each mining parameter, establishing a relation model about the relation between the overlying strata damage ratio of the overlying strata stratum and the mining parameter according to the corresponding relation between the overlying strata damage ratio and different parameter values of the mining parameter; and taking the parameter value of the mining parameter corresponding to the maximum change speed value as the endpoint value of the parameter value range after the mining parameter is optimized, and further determining the endpoint value of the parameter value range after each mining parameter in the plurality of mining parameters is optimized. The mining benefit can be guaranteed, loss reduction mining is achieved to the maximum degree, and meanwhile mining damage can be controlled from the source.

Description

technical field [0001] The invention relates to the field of mining parameter design of mineral deposits, in particular to a mining parameter optimization method, a mining method, a storage medium and computer equipment. Background technique [0002] With the advancement of technology and equipment, the scale of my country's underground coal mines has grown from the one-million-ton level (1-3 million tons / year) in the 1990s to the ten-million-ton level (10-30 million tons / year) at the beginning of this century. year). The continuous improvement of the level of mining and reduction has gradually become an important way to improve the degree of safety, resource recovery and economic benefits of coal mines. According to the intensive development layout, my country's 14 large-scale coal bases account for more than 95% of the country's output. [0003] High-intensity mining is an important method of intensive mining, but it also brings about the problems of rapid surface subside...

AI Technical Summary

Problems solved by technology

However, due to the rapid advancement of high-intensity mining, the large size of the mining face, the large damage range of the overlying strata, the rapid surface subsidence and large deformation, the high degree of damage to the surface and ecology, and the prominent contradiction between resource development and ecological mining area construction, etc., It is difficult to control the degree of surface damage from the source
