A method for early warning of rock burst dynamic disasters

Abstract

The invention provides an early warning method for rock burst dynamic disasters. According to the characteristics of rock burst disasters, an early warning model, an index, and a mathematical model for identification and analysis are constructed from the objective risk of disaster occurrence, defects in preventive measures, and management defects. Downhole sensors, ground servers, and basic data information platforms form relevant early warning technologies and systems. The invention utilizes big data technology to carry out early warning of rock burst disasters from the process, prevents loopholes in each link, and ensures the success rate of early warning and prevention.

Description

technical field [0001] The invention relates to the field of coal mine rock burst prevention and control, in particular to a coal rock rock burst dynamic disaster early warning method. Background technique [0002] From the perspective of energy demand, my country's coal-based energy pattern will not change in a short period of time, and the proportion of coal will remain at about 50% for a long time, and about 95% of coal mining is dominated by underground mining. At present, coal mining extends to the deep at a rate of 10-20m per year. Deep mining has gradually become the norm in the central and eastern regions, and rock burst disasters are becoming more and more serious. After years of development in China's rock burst disaster prevention technology, it is basically clear that the occurrence of rock burst The physical and mechanical characteristics of coal and rock mass, that is, the impact mostly occurs in the area of ​​coal and rock mass that has a tendency to impact an...

Problems solved by technology

At present, coal mining extends to the deep at a rate of 10-20m per year. Deep mining has gradually become the norm in the central and eastern regions, and rock burst disasters are becoming more and more serious. After years of development in China's rock burst disaster prevention technology, it is basically clear that the occurrence of rock burst The physical and mechanical characteristics of coal and rock mass, that is, the impact mostly occurs in the area of ​​coal and rock mass that has a tendency to impact and accumulates a large amount of elastic energy, and relatively available identification techniques, critical values, and prevention techniques have been formed, such as microseismic technology, electromagnetic radiation technology and hydraulic pressure. Fracturing, etc. have formed laws and regulations such as "Coal Mine Safety Regulations", "Measurement, Monitoring and Prevention of Rock Burst", and the "Regulations on Prevention and Control of Coal Mine Rock Burst" is being formulated, but there is a lack of an objective hazard from disasters. In terms of the nature, defects of preventive measures and management defects, etc., the early warning model, index and judgment analysis mathematical model are constructed from the prevention process, and the early warning technology is established to cause the impact disaster prediction and early warning to be missed. The patent of the present invention is a brand-new technical method and system, filling the technical gap
