Key words: scalable。 Coal。 Warehouse mining。 recovery 2. Introduction With the extension of the mine length of service, increase productivity, the mine39。s remaining recoverable reserves will be gradually reduced, the market petitiveness will continue to decline. In our country there are many old stateowned mine due to depleting resources, production of convergence of tension, conflict and so difficult to replace mine, a decline in production, lower benefits, the operating difficulties of the situation. In order to increase production to mitigate pressure on the operators to extend the mine life, most coal mines has increased the corners of coal, coalmining efforts. Against the mine in the coal mining corner, when the widespread use of coalmining law of the Warehouse to the characteristics of Jincheng Coal Industry Group under the Technology Center at the actual needs, through research and development applicable to the Warehouse under the conditions of exploitation of scalable with cantilevered Coal, 3. With the structure of coal Scalable cantilever loaded coal mainly by the rack, cantilever, Rotary, walking, supporting fixed, carrying bodies, hydraulic systems and other parts of position, its shape structure see Figure 1. 1 the crane 2 Doo 3 before the support of 4 emulsion winch 5 walking mechanism 6 Rotating bodies 7 control valve 8 support after 9 rack Figure 1 scalable with cantilevered structure of the coal – rack Rack is loaded coalbearing the main ponents, all ponents are installed in the rack. cantilever Cantilevered from an arm, two arms, threearm, twocylinder telescopic emulsion position, and between the turret connected with Pin. As threearm nested in the two arms, two nested in one arm arm, stretching emulsion in the secondary role of the cylinder, the cantilever stretching movements can be realized, stretching capacity of 3 670mm ~ 8 270mm. On the other hand, two fixed rotating platform of change in the role of Jack, the cantilever can achieve takeoff and landing movements, lifting capacity of: 1360 mm ~ 5 000mm. Rotary agencies Rotating bodies from the turret and fixed rack in the lower side of the two rotary jack in the rotating platform equipped with cantilever, winch and other parts of the emulsion. Rotary jack in the drive, the turret driven cantilever to do about the direction of rotation, left and right direction of the swing angle can reach 45 176。. loading mechanism Emulsion carrying bodies from the winch and rake bucket ponent. Emulsion winch 2 Taiwan, one for heavy use, another Taiwan for a lightload。 characterized by the emulsion motor powered motor rated pressure of 12. 5M Pa, traction speed, traction 10 kN ~ 20 kN. Trailing bucket volume is cubic meters of coal loaded containers from the emulsion winch drag achieve reciprocatin
