Box bracket fill mining recovery approach Party
1 day ago Shanghai, Antarctica
( 1 ) Recovery sequence. When filling system applying a multi-stage block stent recovery , the stage should advance its lead distance must be higher than 50m. Segment employing 25 ~ 30m high , the recovery phase may be left in between the two stages , resorted to filling the mine and had been carried out in two stages , independently of one another .
high quality crushers and mills
Box bracket filling technique is slicing disk or from the upper footwall direction . A slicing can , but to enhance the strength from the mining , recovery generally use two layered whilst the next hierarchical ahead 8 ~ 10m, we are able to use 3 to four hierarchical recovery even though the subsequent certainly one of the layered lead layer two to 3 boxes , but recovery may possibly not be more than 4 layers .
( 2 ) off the mine. Box bracket filling system comparatively soft ore mining , the usage of hand-dug In most situations, when slightly harder ore , mining picks obtainable . When the ore is difficult, using drilling and blasting off mine. Shot hole depth does not exceed 1.0 ~ 1.2m, blasting the amount need to not be too much to make sure the stability from the pillars with the box .
successful mining process solutions
( 3 ) bedding . Stope ore loss rate and whether or not the wooden plate and high quality related. From our expertise and that of the Soviet Union : the laying groundwork board pad than without filling compound can lower the loss of minerals from four to 8 occasions. If Yunnan old tin mining Malargue 426 orebody is no loss of plate filling compound price of 12 %, and after laying down to 1.5%.
Old tin popularized commissure wooden pallets, the high-grade ore at plate holes and also a layer of canvas or burlap to recover ore powder .
( 4 ) Conveying . Ore and filling material to maximize the use of gravity humping . As a little dip or occurrence ore complex ore employing gravity and filled with difficulties or need more boring and chute filled patio , we are able to use a small tub or small electric rake in stope ore haulage and filling material .
compelete Crushing plant Porject
( 5 ) to set up the box . Box set is the recovery of your most important processes, starting from the stage of a long tunnel to transport the beam erection in the first hierarchical . Beams for the extended length of two in the box . Erection from the initial hierarchical particular strict needs , you should make use of the horizontal ruler , angle square or plumb bob to check calibration.
A part of the four corners from the box to utilize brief wooden tenon wedge pad . Box set encounter the upper and lower plate , should really not damage the surrounding rock , to help keep the upper and reduce rock integrity .
( 6 ) filling. To be able to proficiently control the roof , requiring high-density filling, filling the space attributable to adopt more than 75 to 85% empty region. Block with the filling material shall not exceed 80 ~ 100mm. So that you can protect against dilution , between the filling and the ore body to become separated planks or logs . Horizontal unfilled boxes must not exceed four. Unfilled height of not more than two boxes ; multi- tiered recovery immediately after face two boxes unfilled height of not greater than two boxes ; great stress or old hole stope mining area , not simply filling height Enable a box .
