Key Technologies for Controlling Mining Dynamic Disasters
摘要
Deep coal resources are the main backup energy security for our country in the future. China is the country with the largest scale, difficulty, and number of deep coal mine construction in the world. The safe and efficient mining of deep coal resources is a key issue that most coal mines in our country must face. Typical mining dynamic disasters include rock burst, mine water inrush, and large deformation of roadway surrounding rock, which are sudden, sharp, and violent. They are extremely complex dynamic phenomena that occur in coal mine mining, essentially induced by stress field disturbance or strain increase during mining process, leading to the birth, development, and penetration of micro-fractures until instability occurs.
