Shaanxi Coal Chemical Group conquers the safety production problem of coal and oil symbiosis mine

Through a decade of scientific research, Shaanxi Coal Chemical Industry Group has overcome the difficult safety of coal and oil symbiotic mines in the world. 16 safe and efficient coal mines have been built in areas with extremely complicated geological conditions. The death rate of millions of tons of coal mines is only national average. 1/10 of the level.

The proven reserves of coal in the Huangji Luoji coalfield where the Shaanxi Coal Chemical Group is located is 13.92 billion tons, which is a good power coal and gasification coal. However, the geological mining conditions are complex, and gas, oil, gas, fire, water and other disasters occur frequently, which seriously threatens the safe mining of coal mines. To this end, the group organized relevant scientific research units to jointly tackle the problem, and through years of continuous efforts, discovered the disaster-causing mechanism of coal-oil-water symbiotic mines, and proposed a new concept of coal-fired symbiosis mine gas prevention and control as the core of fire prevention, and built a coal-oil symbiotic mine. The coupled disaster prevention and control early warning system has created a coal mine oil and gas symbiotic mine coupling disaster prevention and control technology system. It has been promoted and applied throughout the coal-fired symbiotic mine in the Ordos Basin. There has not been a coal mine safety accident with more than three deaths, and significant social benefits have been achieved. Economic benefits.

It is understood that around the complete resolution of the major technical problems in the safety production of coal-fired symbiotic mines, Shaanxi Coal Chemical Group has proposed a new concept of coal-fired symbiosis mine gas prevention with fire prevention as the core and gas extraction, and developed a coal-fired symbiotic mine coupling disaster. Collaborative prevention and control early warning system, the coal and oil and gas symbiotic mine coupling disaster prevention and control technology system was established, and 3 invention patents, more than 60 utility model patents, 2 software copyrights, 6 monographs and more than 200 papers were published. It also promulgated 2 national coal industry standards and dozens of Shaanxi Coal Chemical Group enterprise standards, trained a group of doctoral masters and senior engineers and technicians in the first line of coal mines, and won the first prize of 2014 China Coal Industry Science and Technology.
