[Abstract]:The fracture activity of surrounding rock, the support problem and the complexity of mine pressure in loose unstable coal seam mining with large dip angle lead to the low output of working face, the high labor intensity of workers and the bad working environment, which lead to the frequent occurrence of such problems as low output of working face, high labor intensity of workers and bad working environment. Therefore, it is urgent to systematically study the mining theory of loose unstable coal seam with large dip angle and to study the complexity of fully mechanized mining system. In this paper, the research on mining technology and system complexity of large dip coal seam at home and abroad is reviewed, the significance and function of complexity research in dealing with the complexity of large dip coal seam are pointed out, and the complexity of fully mechanized mining system in loose unstable coal seam with large dip angle should be studied under the guidance of the idea and method of system complexity, and the complexity of fully mechanized mining system in loose unstable coal seam with large dip angle is studied. The concrete research results are as follows: (1) aiming at the problem of fully mechanized mining technology in loose coal seam with large dip angle, based on the basic theory and method of system complexity science, the complexity of long wall fully mechanized mining system in loose unstable coal seam with large dip angle and its complexity characteristics are analyzed. The main factors affecting the complexity of fully mechanized mining system are qualitatively and quantitatively analyzed.
