Safety and high efficiency adaptability evaluation of coal mine intelligent fully-mechanized mining face

In order to study the influence degree of coal seam occurrence,geological structure characteristics and mining technical conditions on intelligent fully-mechanized mining face,and master the adaptability of intelligent fully-mechanized mining face under different conditions,the intelligent comprehensive mining face of Shendong Coal Group was investigated.Through the technical consulting and analysis of the geological conditions of the working face,mining technical conditions,equipment level and the existing problems,the main controlling factors affecting the adaptability of intelligent comprehensive mining were obtained,including coal seam stability,working face length and degree of fault impact.Therefore,the index system of coal mine intelligent comprehensive mining adaptability evaluation was summarized.Based on the fuzzy comprehensive evaluation method,the evaluation indicators were quantified.And use the AHP method to determine the factor weights.Then establish the adaptive evaluation model for coal mine intelligent comprehensive mining,and the intelligent evaluation of mining efficiency and safety of intelligent fully-mechanized mining face was realized.
