Geological Support Technology Framework System for Mining Induced Disasters and Damage Reduction Mining of Geological Conditions in Western Mining Area

  • Objective It is difficult to change the main energy status of coal in our country in the short term, which is the guarantee of our energy development. The large-scale and high-intensity mining of coal resources damages the geological environment of coal mining areas, and at the same time leads to disasters such as water inrush and rock burst. Method Based on the interdisciplinary characteristics of coal mining damage prediction and loss reduction geological support, highlighting the disaster control mechanism and mining induced disaster mode of geological conditions, emphasizing the multi temporal and multi field response of coal mining mode and geological structure evolution, analyzing the coupling mechanism of geological condition material field, energy field, and information field under mining effect, clarifying the mapping relationship between damage mode and key parameters of warning information, and forming a safe and efficient mining support strategy and loss reduction and disaster control engineering technology system. Results and Conclusions The research approach is "disaster prone environment →damage mechanism → process response → damage prediction → disaster prevention and reduction", and the technical route is "coal mining geological environment conditions → geological structure evolution laws and damage modes → multi physical field evolution full time and space information response → damage monitoring and prediction warning → loss reduction guarantee engineering technology". The core content includes: (1) analyzing the spatial relationship and genetic relationship between geological conditions and typical disaster causing geological bodies, constructing high-precision three-dimensional geomechanical models, clarify the mapping relationship between geological structure, mining conditions, and damage modes, and establish a database of characteristic parameters for the main control elements. (2) Construct an engineering geomechanical model under the mining effect, study the spatiotemporal evolution characteristics and damage mechanisms of geological conditions structure under the influence of mining methods, spatial layout, mining rate, etc.; propose damage mode identification method that considers the evolution law of key structural failures in geological formations. (3) Obtain the response characteristics of multi-source information in the context of geological structure evolution during the mining process, propose damage pattern recognition standards under the influence of main control parameters; clarify the mirror relationship between fissure field, stress field, seepage field and geophysical field information parameters, and establish a comprehensive spatiotemporal information mapping model based on the coupling response of geological conditions material field, energy field, and information field. (4) Building a comprehensive, multi-directional, active and passive integrated multi-source monitoring system from the ground, drilling, and rapid analysis models, and propose intelligent prediction models and methods for coal mine mining damage. (5) Build a disaster reduction and control sy stem based on the analysis of damage sources, damage modes, damage dynamics, damage channels, and the evaluation of damage reduction technologies and effects, in order to pursue the coordinated development of coal safety mining and geological environment protection. This article deciphers the contradiction between resource development and geological environmental constraints, providing a scientific basis for safe and efficient coal mining, di saster prevention and loss reduction based on geology, mechanics, and physics.
