Research status of hydraulic coal and gas outburst prevention and control technology
China is one of the countries prone to coal and gas outburst accidents.In the early days of the founding of the People's Republic of China,prominent accidents occurred frequently,causing serious casualties,equipment damage and economic losses.In recent years,some scholars have tried to use the physical model to simulate the phenomenon of coal and gas outburst and study its mechanism.However,due to the complexity and non-reproducibility of coal and gas outburst disasters,the research on the mechanism of coal and gas outburst is still in the hypothesis stage.In order to effectively reduce the risk of coal and gas outburst accidents,coal and gas outburst prevention and control technology came into being,and achieved remarkable results,the probability of coal and gas outburst accidents is greatly reduced.In the prevention and control technology of coal and gas outburst,hydraulic prevention and control technology is widely used.The purpose of this paper is to briefly explain the mainstream hypothesis of coal and gas outburst,analyze the action principle of hydraulic prevention and control technology,discuss the research status of hydraulic prevention and control technology,and put forward the existing problems and future development trend of the current technology.
