The Research Of Coal Bed Light Caving Fully Mechanized Exploitation Within Complicated Conditions

In this paper, the possibility of using light caving fully mechanized exploitation is analyzed and reasoned, in allusion to the characters of Zhaizhen colliery, which has multiple faultage and is difficult to support its composite roof. Based on the theory of industrial engineering , transformation from slap-up general exploitation to light caving fully mechanized mining was put into praactice gradly, of some aspects as equipment selecting, construct technics, working organization and safety management, according to a process as follow steps: presenting project, establishing work organization and accessorial technic measures, putting caving fully mechanized mining of typical working face into practice , summarize and improvement. In accordance with the actual conditions, working techniques are optimized. In allusion to difficulties of transport and fixing caving fully mechanized mining support bracket, and difficulties of the facts of many repair slice eyes in faultages and high move evacuate frequency, a special troop is established, safety and efficiency in special segment are realized, the cumber factor in mining is eliminated. New teaching methods like making slides with concepts of accident cases and technological practices are used for workers training. In less than a half years, the generating technics of all four mine fields are changed from advanced general exploitation to light carving fully exploitation. At the same time, many innovation were made to fit for this new technics, as overpassing the faultages without rocks and wide laneway enlarge with mine machine, which effectively insure the successful actualizeing of carving fully mechanicis technics within complicated conditions. Because of the above measurees, this technology is successfully full popularized, difficulties problems of low resource reclaim rate, high work intensity, going against safety production are radically solved. It makes great contribution to constructing safe and efficient mine.
