Embodiment Construction

[0031] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions protected by the present invention will be clearly and completely described below using specific embodiments and accompanying drawings. Obviously, the implementation described below Examples are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in this patent, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this patent.

[0032] This embodiment provides a composite type coal-rock gas dynamic disaster early warning method, such as Figures 1 to 3 As shown, the methods include:

[0033] S1: Through geological survey, on-site underground measurement and mining production to obtain coal seam occurrence anomalies, geological structure anomalies, high gas, impact tendency, stress concentration and outburst omen ...

Abstract

The present invention provides a composite coal-rock gas dynamic disaster early warning method. According to the composite disaster occurrence and prevention characteristics, the early warning model, index and judgment analysis mathematical model are constructed from the objective risk of disaster occurrence, defects in preventive measures, and management defects. Relevant early warning technologies and systems are formed based on downhole sensors, ground servers, and basic data information platforms. The invention uses big data technology to carry out compound disaster early warning and prevention 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 gas prevention and control, in particular to a composite coal-rock gas 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 has brought new problems of coal-rock gas dynamic disasters. The two most typical manifestations of coal-rock gas dynamic disasters in mines in my country are coal and gas outburst and rock burst, but the gas-bearing coal-rock dynamic disasters in the central and eastern regions show a dual dynamic characteristic of impact tendency and outburst danger. , from a sin...
