Abstract

The invention discloses a prediction method for mine dynamic disasters. The method comprises the steps of performing macroscopic analysis on a disaster background of a mine lot according to natural geological conditions, including configuration, tectonic movements, natural earthquakes, ground stress and the like in the analysis of natural geological dynamic conditions of the mine lot, so as to realize the preliminary evaluation on the structural environment, stress environment and energy environment of the mine lot; performing the primary prediction of the mine dynamic disasters, realizing the assessment of risks on the dynamic disasters generated in a coal bed based on the natural conditions of the mine, and realizing the prediction and regional division on the dangerousness of related coal layers of the whole mine; performing the secondary prediction on the mine dynamic disasters, fully considering the engineering effect and gas extraction engineering based on the primary prediction, so as to realize the prediction on a working surface. According to the method, the digitization and visualization of predicted results can be realized, guidance can be provided for the prevention of the mine dynamic disasters, scientific basis can be provided for adopting controlling measures in a targeted way, and the economic waste caused by blindly adopting the measures can be prevented.

Description

technical field [0001] The invention belongs to the field of mine dynamic disaster research, in particular to a mine dynamic disaster prediction method. Background technique [0002] Coal and gas outburst, rock burst and mine earthquake are collectively referred to as mine dynamic disasters, which are the main dynamic disasters in coal mines. my country is one of the countries with the most serious mine dynamic disasters in the world, and the number of mines with more than two kinds of dynamic disasters is gradually increasing. In the next 10 years, a considerable number of mines will enter deep mining in China. Deep mining is a common problem faced by the mining industry worldwide. The depth of mine mining in major coal-producing countries in the world is increasing year by year, and the mining depth of some mines in developed countries such as the United States, Germany, and the United Kingdom has reached 1500m. In our country, with the development of the national econo...
