Intelligent Mining Safety Guarantee System and Key Technologies for Coal Seams with Extremely Complex Conditions
In view of the problems existing in the intelligent construction of coal seams with extremely complex conditions,the progress of intelligent safety guarantee technology of coal mines in China was introduced,the key technologies of gas prevention and control,mine fire,water disaster control and personnel and equipment collaborative scheduling in coal seams with extremely complex conditions were expounded,and the safety guarantee system of intelligent mining working face was established.It was emphasized that the basis of intelligent mining is to establish an accurate geological perception model.Combined with the engineering practice of Huaibei mining area,the solution to the problem of intelligent safety guarantee of coal seam under extremely complex conditions was put forward,which mainly included geological perception,risk prevention of gas,water disaster and fire,as well as big data platform equipment personnel scheduling.Based on high-density three-dimensional seismic precise geological support technology,high-efficiency directional drilling technology for high-gas coal seams,mine water disaster protection technology,mine fire online monitoring and early warning technology,as well as overall scheduling architecture of mine personnel and equipment,mine safety risks and production costs were reduced.The study can provide a reference for engineering practice under similar conditions and provide a technical path for building an intelligent mining safety guarantee system for extremely complex coal seams.
