Study Of Series Of Machineries And Mining Techiques Of In Fu LL Mechinized Sublevel Mining

This text regards prosperous 5318 working ranges of village colliery of group of mining industry of Yanzhou as and studies the experimental target , to putting the defect of the complete sets existingly and comprehensivly, break connecting rod and base such as the hydraulic pressure support , blast down the roof coal rear conveyer transport ability little and dependability bad and person who reprint , breaker use short-lived and getting complicated structure, through to putting select the optimum seeking type comprehensivly, form a complete set overallly and designinging of complete sets, to comprehensive to put complete sets go on redesign and transformation, in order to is it put adaptability and dependability of complete sets while being comprehensive to improve, solve the problem that put as a lot of as possibly comprehensivly while exploiting and exist, form one is it put coal technological requirement, form a complete set of good performance to accord with , high yield high-efficient , high dependability comprehensive to the complete sets are set free finally, this text regards surveying at the scene as the foundation, has carried on the theory to analyse through similar material simulated test and numerical simulation on this basis, high-efficient to show if craft carry sport of coal (board ) destroy law , put coal way and put coal parameter ,etc. carry on research while being comprehensive to high yield. Have formed one set and suitable for comprehensive complete sets which put the process conditions according to the request of high- efficient high dependability of the high yield , including: Support of hydraulic pressure of coal that ZFS6200/18/35 type blasts down the roof, shave board conveyer , Model SZZ1000/375 loader , Model PCM200 breaker ,etc. in the Model SGZ900/750 rear. Show coal parameter and choice of way in is it carry coal (board ) sport destroy law and blast down the roof coal at the support foundation of characteristic to study, put coal principle of time is it two adopt first craft set according to high rate of extraction , low ash free to select finally little.
