Precise dynamic outburst prevention method based on transparent space geophysics

Abstract

The present invention relates to a precise dynamic outburst prevention method based on the transparent space geophysics, and belongs to the field of mines. The method comprises: using the theoreticaltechnology of the transparent space geophysics to establish a spatial digital analysis model, combining with the modern high-precision geological prospecting technology and equipment to precisely identify and classify the regional geological structure of the mine, and determining the influence of coal and gas outburst key geological bodies on the gas occurrence; using a big data cloud computing technology to analyze the correlation between various factors, and precisely predicting the multi-indicator coupling of outburst risks in the coal seam area; and analyzing the correlation between data information, and establishing a scientific gas drainage model for mines according to specific procedures to achieve optimal scientific drainage of mines. According to the method provided by the presentinvention, parameters of each link in the outburst prevention process are dynamically managed in an online manner, comprehensive analysis is carried out in real time, the laws of coal and gas outburst are accurately grasped, and multiple precise measures are provided for dynamic outburst prevention, so that blindness of outburst prevention work is reduced, and the costs of outburst prevention engineering are saved.

Description

technical field [0001] The invention belongs to the field of mines and relates to an accurate and dynamic outburst prevention method based on transparent space geophysics. Background technique [0002] The main coal-bearing basins in my country all have complex structural evolution backgrounds, and the multi-stage structural rubbing, extrusion, stretching and other superimposed transformation movements lead to complex and changeable geological structures in coal-bearing basins, which increases the difficulty of coal mine gas control . With the rapid development of the national economy, my country's shallow coal resources will gradually decrease or even be exhausted, and coal mining will gradually shift to the west and deep areas. More and more mines will face many severe deep mining problems (such as: complex and changeable geological structure, high gas enrichment, coal and gas outburst, etc.). [0003] Coal and gas outburst is an extremely complex dynamic phenomenon. The ...

Problems solved by technology

[0005] Gas drainage is one of the main means to solve gas disasters in coal mines. However, the current drainage technology is relatively simple, and the drilling design in different geological structures and areas with changing gas content is not targeted, resulting in waste of drilling holes, and the drainage effect is not ideal. Serious Restricting the succession of mine production; in addition, the drilling construction process is difficult to control, the drilling trajectory cannot be accurate, there is a drainage blank zone, and the regional outburst elimination effect is not ideal

[0006] For mines and mining areas, regional prediction is contact type, and most of them are static evaluation results. It is impossible to conduct real-time and dynamic risk evaluation and analysis of the entire process from design, tunneling to mining within the working face section, and it is difficult to timely Provide decision-making assistance for staff in a timely manner; lack of methods and means to effectively manage basic information data, staff cannot obtain the required information conveniently and quickly; existing data on gas, geology, and outburst prevention measures are mostly expressed in text. Lack of effective expression and analysis of spatial data, unable to reflect relevant information vividly, intuitively and truly
