Sell Shandong Quanxing Mining Group Quanxing Coal Filling Equipme

详情

Quanxing Mining Company (the original name is Quanshang Mine), located in Tengzhou County, is the core enterprise of Quanxing Mining Group. The mine area is *0.7 square kilometers, the geological reserves is *5.*3 million tons, the recoverable reserves is *6.*6 million tons and the designed annual production capacity is **0 thousand tons.
Basic plan:
The filling system adopts “fly ash high water filling” technology, and uses water, fly ash and cementation powder to produce “slurry like paste” filling material with *0% mass concentration. The filling material can flow naturally to stope through drilling and underground laying piping, the whole system from cementing material proportioning production to filling slurry proportioning production adopts fully automation accuracy metering control, and achieves that one roadway serves for an exploration area, which can reduce thousand tons of tunneling ratio and manpower. In a word, the system possesses the advantages of simple operation, high filling speed, reliable operation and good filling effect.
Technical innovation:
Of fly ash cementing automation exploration system, piping length is long (about ***0m), upscaling is large (about *2.8). The gravity-flowed filling upscaling is second to none in China.
     It adopts new-type filling cementing material.
Central control system adopts WinCC human-computer interface, which can carry out remote commissioning and system maintenance through network.
 
The filling cost is low.
Application achievement:
Adopting filling exploration technology can not only reliably protects ground village buildings, but also exploits coal resources at maximum quantity. It can fully recover the coal column under village, reasonably exploit the coal together with deep coal bed, ease the contradiction of continuous mineshaft tension and promote the healthy and stable development of the mineshaft.
