Monitoring and early warning system and method for complex dynamic disasters in deep water-rich and thick coal seam mining

Abstract

The invention provides a deep water-rich overlying strata thick coal seam mining composite power disaster monitoring early warning system and method. The method includes the steps: acquiring coal seammining technical conditions and mine hydrogeology base data; preliminarily judging possible disaster conditions of a deep thick coal seam mining working surface; evaluating and analyzing working surface rock burst dangerousness by a rock burst disaster analysis and early warning module in real time; performing working surface sudden water burst disaster analysis and judgment on the acquired information by a working surface sudden water burst analysis and early warning module; giving working surface composite power disaster occurrence mechanisms and early warning results by comprehensive analysis of an early warning platform; comparing the results and early warning standards to provide a treatment method. The system is scientific, safe, practical and high in operability, and integrated monitoring and early warning and integrated control of deep water-rich overlying strata thick coal seam mining composite power disasters are conveniently achieved.

Description

technical field [0001] The invention relates to a monitoring and early warning system and method for composite dynamic disasters in deep water-rich and thick coal seam mining, and is particularly suitable for real-time monitoring and early warning of water inrush-rock impact composite dynamic disasters in the mining process of high-strength coal seams in deep water-rich environments. Background technique [0002] With the further increase of mining scale and intensity in the western mining area, significant changes have taken place in the mining stress field, dynamic response characteristics of coal and rock mass, and energy accumulation and release laws during the mining process. 630m, has become the first mine to experience rock burst phenomenon; Gansu Huaneng Group Hetaoyu Coal Mine's auxiliary shaft depth has reached 975m, shaft engineering mine pressure is severe, and support is difficult; the mine pressure in the "deep" mining area in the western mining area shows posit...

AI Technical Summary

Problems solved by technology

Due to the complexity and particularity of the geological and hydrological conditions in the western mining area, there is an obvious correlation between mine earthquakes, rock bursts and induced coal and gas outbursts, water inrush and other composite dynamic disasters in high-intensity mining mines. The rock burst early warning technology commonly used in coal mines can no longer meet the needs of safe production
