In order to realize an accurate collection,intelligent analysis and effective control of the data at each monitoring and control point of the coal shearer,a study was conducted on a full automatic coal shearer with a self control and monitoring control system. Based on an intelligent control and monitoring control system of MG250 /595- WD electric haulage coal shearer as a study object,with the cutting motor load and the pressure variation of the front and back cylinder chambers when the coal shearer drums contacted with different seam,a new coal and rock recognition technology and memory cutting technology as well as the data transmission in underground mine and other technologies applied,finally,realized a manual control,autonomous control and host computer remote control modes of the coal shearer and a real time monitoring and control of related working parameters. During a trial period of the coal shearer and the matched monitoring and control system in No. 152304 coal mining face of Gushuyuan Mine,a coal mining with 300 000 t was completed,an accuracy rate of the coal and rock recognition in the industrial trial reached at 80% and the safety coefficient,coal cutting efficiency and automatic degree of the mine production were effectively improved.
