Abstract

The invention provides a method for evaluating the complexity of gas geology based on a comprehensive index of gas geology. A comprehensive index of gas geology is constructed with the gas geology basic data, the comprehensive geological structure and the gas and coal structure to evaluate the complexity of gas geology. The limitation of the traditional method for evaluating the complexity of gasgeology according to a single or a few factors is avoided. The method of the invention considers all factors contained in a gas occurrence environment. A new way of semi-quantitative evaluation of thecomplexity of gas geology is realized. A foundation is laid for the rapid and simple prediction of the coal and gas outburst danger level of a coal seam. The method for evaluating the complexity of gas geology is simple, easy to operate, and more scientific and systematic, can reflect the complexity of gas geology more accurately, provides a direction for more scientific construction layout of mines, and can be widely promoted and used.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety, and relates to a coal mine gas prevention technology, in particular to a method for evaluating gas geological complexity based on gas geological comprehensive indicators. Background technique [0002] Gas prevention and control is the top priority of my country's coal mine safety work. With the deepening of research on gas disaster prevention and control, more and more attention has been paid to the study of gas disasters from the perspective of gas geology, especially the mechanism and prediction of coal and gas outburst. The study found that the more complex the gas geological conditions for coal seam gas occurrence, the greater the risk of coal and gas outburst. [0003] At present, gas geological research is mainly to study the influence of one or several factors on the occurrence of coal seam gas qualitatively (or quantitatively) by studying the influence of regional geological stru...
