[Abstract]:The prediction of outburst risk is one of the most important problems in China's outburst prevention work. In order to strengthen the technical level and disaster prevention capability of coal and gas outburst prevention in coal mines in China, the safety situation of coal mines is improved. In order to improve the accuracy of mine outburst prediction and to guide the work efficiency, this paper studies and analyzes the dynamic prediction of coal and gas outburst in different tunneling working faces. Taking the characteristics of gas emission from coal and gas outburst disasters in China and typical fully mechanized mining and blasting faces in Huainan mining area as the research objects, the dynamic characteristics of gas emission are studied. The influencing factors and law of dynamic gas emission in tunneling face are put forward. The prediction method of determining coal and gas outburst by using dynamic gas emission parameters is put forward, and different tunneling techniques are determined. The prediction sensitive index and critical value of heading face in different working procedures are developed and the equipment of dynamic monitoring system for gas emission is developed. This paper has carried out the following aspects of research content: 1. The paper has investigated the coal wall, gas emission and influencing factors of typical fully mechanized coal face and blasting face in Huainan mining area on the spot. The law of dynamic gas emission in working face under different tunneling techniques in Huainan mining area is determined, and a mathematical model for predicting dynamic gas emission in tunneling face is obtained. In this paper, the prediction method of dynamic gas emission in tunneling face is established, which is used to summarize the outburst situation in Panyi Mine, and through theoretical analysis and on-site investigation and measurement, A sensitive index for predicting the dynamic emission of outburst dangerous gas in 11-2 fully mechanized mining face and 13-1 coal blasting face is determined. The prediction indexes are respectively the maximum gas emission rate index and the cumulative gas emission per unit coal quantity per unit time. The prediction indexes are the maximum gas emission rate index and the gun emission rate index after gunning. 30 minutes after the cumulative gas emission index, At the same time, the critical value of prediction sensitive index is determined. The laboratory has developed a dynamic gas emission monitoring system for KJ338 outburst. The system predicts coal and gas outburst risk by monitoring and controlling the characteristic index of gas emission in tunneling face. In order to improve the safety situation of coal mine, a new method and method is added for the non-contact prediction in China, and the reliability and continuity of the prediction are improved. A new equipment is provided for reducing disaster accidents, especially those caused by unexpected events that are difficult to detect. A dynamic Prediction method of Gas Emission in tunneling face and dynamic Monitoring of Gas Emission established by the Institute. The technology of surveying can realize the advance dynamic prediction of the heading face. In order to forecast the outburst danger of the working face in real time, and to monitor and warn the working face in real time, the accuracy of predicting no outburst danger can reach 100%, which is of guiding significance to reasonably predict the outburst danger in the heading face and to formulate effective measures to prevent outburst. It is helpful to the safe production of mine and the exertion of high yield and high efficiency advantage. At the same time, the use of this technology and equipment can greatly reduce the quantity of outburst prediction and measures to prevent outburst, and greatly liberate the productive forces. The content of the study not only raises the level of continuous monitoring of dynamic gas emission in China, but also further improves the ability of preventing and controlling gas in coal mines, which ensures the safe production of mines and has remarkable economic, social and environmental benefits.
