Abstract With the extension of coal mining to the deep part of the mine, the geological structure is becoming more and more complex. In addition to the layout of the long tendency distance and large mining width working face, the hidden disaster-causing factors inside the working face bring a series of safety hazards to the safe and efficient mining of the working face, and the geological guarantee technology must be further improved. Based on the actual working experience of No.6272 face in Lvjiatuo Mine, this paper summarized and put forward the ideas of exploration, prediction, prevention and control of hidden disaster-causing factors in long tendency distance and large mining width working face from the aspects of comprehensive analysis of basic data, strengthening the application of geophysical and drilling methods and strengthening tracking and observation on site.
