The most important solid industrial waste material of industry, the stacking of CHARACTERISTICS OF TAILINGS SAND can cause environmental protection very big pressure.In existing mine
In filling technique, in depth limit, the utilizations of crude tailings is on strength of filling mass far from meeting mine safety
The requirement of mining.
At present, using tailing as the classified tailings filling process of aggregate, crude tailings high dense fill technique and paste body filling work
Skill has technically achieved important breakthrough and has been widely applied；But the profit of middle crude tailings in depth limit
With being but extremely restricted, which is because, one is the obturation that it is prepared into, laminated segregation is serious, and whole homogeneity is poor.
Second is that its filling slurry dehydration prepared is slow, the early strength of obturation is low.Third, its filling slurry prepared will ensure to reach
The lower intensity requirement to cemented fill, cementitious material additive amount is big, causes filling cost high, influences the economic benefit of mining.
Thus the utilization rate of crude tailings is limited, can only promoted and applied on to cemented-method or open-stope method minority mine.
Ensure mining safety production, constantly reduce filling cost, be a main skill for ensureing Mine Sustainable Development
Art measure.Therefore, it using crude tailings as main filling aggregate, adds a small amount of cement and is filled, be to solve crude tailings to utilize, reduce
The use of back-up sand is processed, tailings is reduced and stacks pollution, reduce the important channel of filling cost.Therefore, it is necessary to further study
Develop a mine tailing filling new model, to reduce filling cost and reduce discharge of the tailing waste material to earth's surface.
Therefore, it using crude tailings as main filling aggregate, adds a small amount of cement and is filled, be to solve crude tailings to utilize, subtract
The use of back-up sand is processed less, is reduced tailings and is stacked pollution, reduces the important channel of filling cost.
Invention content
The purpose of the present invention aiming at insufficient existing for above-mentioned prior art, provide it is a kind of can efficiently use crude tailings,
Tailings waste material is reduced to surface discharge, mitigates the pollution to environment, the Desending slicing route of filling cost expense is greatly lowered
The placement method of mining underground goaf.
The purpose of the present invention is what is be achieved through the following technical solutions.
A kind of placement method of Desending slicing Drift stoping underground goaf, it is characterised in that made with mine ore dressing crude tailings
For aggregate, using portland cement as cementing agent, filling slurry is configured to, being delivered to underground goaf by pipeline self is filled
It fills out.
The placement method of a kind of Desending slicing Drift stoping underground goaf of the present invention, it is characterised in that be configured to fill
During slurry, cement additive amount is the 12%-15% of crude tailings weight, and the weight concentration that contains admittedly into filling slurry being configured to is 70%
~75%.
The placement method of a kind of Desending slicing Drift stoping underground goaf of the present invention, it is characterised in that by pipeline certainly
Stream is delivered to underground goaf and carries out stowing operation, and filling slurry is to be filled with to be placed in underground goaf and underground goaf sky
Between in the matched mould bag of shape.
A kind of placement method of Desending slicing Drift stoping underground goaf of the present invention, it is characterised in that the mould bag
For middle water mould bag.
A kind of placement method of Desending slicing Drift stoping underground goaf of the present invention, it is characterised in that the casting resin
Slurry is that the feed pipe from mould bag bottom is filled with mould bag.
A kind of placement method of Desending slicing Drift stoping underground goaf of the present invention, Desending slicing Drift stoping underground
The stowing operation in goaf, the equipment of use include being located at earth's surface tailing filling slurry preparation system and underground filling pipeline system
System fills stope slurry decompressor and pressure detecting and slurry flow control valve, fills mould bag；The stope slurry decompression
Device will meet filling pressure filling to mould bag and be adjusted, and the filling mould bag of use will adapt to fill route specification and stronger
Resistance to compression and infiltration ability.Its arrangement form can ensure that the abundant and top of fast dewatering and the filling of mould bag and the obturation of left and right connect
It touches.
Its attal meets the high concentration upper flow regime feature of filling slurry, and with relatively low with when control parameter
Cement additive amount.
A kind of placement method of Desending slicing Drift stoping underground goaf of the present invention is filled into the slurry tool in goaf
There is the features such as dehydration is fast, and early strength height, obturation good integrity, pipeline are stablized, crude tailings can be efficiently used, filled into
This is low, depressurizes filling filling technique as the mould pocket type placement method and filling slurry of filling aggregate by the use of crude tailings, can be true
Obturation under guarantor into mining with stowing as work top plate reaches the mass intensity requirement of technical standard.And it can reach effective profit
With crude tailings, tailings waste material is reduced to surface discharge, mitigates the pollution to environment, the mesh of filling cost expense is greatly lowered
