Problems solved by technology

Aiming at the inhomogeneity and anisotropy characteristics of coal and rock mass, although relatively mature stress testing methods and means have been formed, the existing stress measurement technology is laborious, time-consuming and cannot be measured when the geological conditions are poor, which results in underground surroundings. Rock support and disaster prevention require more stress parameter data, the more difficult it is to provide, and so far there is no intelligent and rapid stress measurement method and technical equipment

Abstract

The invention provides a fast and intelligent method for measuring the stress characteristic index of coal and rock mass. The fast and intelligent measurement method for the stress characteristic index of coal and rock mass is based on the coal seam gas geological map and the gas concentration value of the coal mine monitoring system. Through mathematical processing and system development, it can solve geological problems. Unable to measure the stress in the abnormal area, and realize the rapid and intelligent reflection of the stress of the coal and rock mass.

Description

technical field [0001] The invention relates to the field of coal mine gas prevention and control, in particular to a method for quickly and intelligently measuring stress characteristic indexes of coal and rock mass. Background technique [0002] From the perspective of energy demand, my country's coal-based energy structure will not change in a short period of time, 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, and deep mining will gradually become the norm, and the role of in-situ stress in coal mine surrounding rock support and disaster prevention is becoming more and more important. Aiming at the inhomogeneity and anisotropy characteristics of coal and rock mass, although relatively mature stress testing methods and means have been formed, the existing stress measurement technology is laborious, time-consuming and ...
