Description
Technical field
The present invention relates to a kind of mineral industry technical field, refers specifically to a kind of dust-removing method of Underground Metallic Mines.
Background technology
Effect of the ramp in mine industry is particularly significant, as the second important escape way of mine, also as more
The air intake passage in individual production stage casing, while substantial amounts of roping task is also carry, for the enterprise in the north, underground bar of digging up mine
Part is more dried, and caused dust is very big during roping, and after vehicle is run over, dust concentration reaches 48.5-57.3mg/
m3, it is and in the prior art, general to use sprinkler depositing dust operation, dust-laying effect clearly, but due to ramp wind speed
It is higher, it is air-dried, underground air humidity is only 27%, although watering and lowering dust is quick at that time, during due to its effective dust suppression
Between it is short be only 2-3 hours, and waste water resource, dried again soon after watering every time, watering 3-5 times, can not still meet daily
It is required that its feature is：Dust-producing amount is big, and the time is more continuous, and Polluted area is wide, very serious for subsurface environment destruction, therefore
Ramp depositing dust work during roping operation is that subsurface environment improves a very important break-through point.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, there is provided a kind of dust-removing method of Underground Metallic Mines,
This method depositing dust and water-saving result are obvious, and in the case of daily watering once, watering standard is 0.5-1.0kg/m2, air
Humidity 25-30%, moisturizing can be continued more than 60 days, watering number can not still meet to require by original daily 3-5 times, to now
Daily watering once, just can be by environment dust concentration by original 48.5-57.3mg/m3It is reduced to 1.8-3.8mg/m3；In addition,
Also saving substantial amounts of artificial and vehicle abrasion cost, the especially dust content in air ambient has significant decline, improves
The working environment effect of underground labour is clearly.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of dust-removing method of Underground Metallic Mines, dust suppression agent solution is sprayed in ramp, is comprised the following steps：
The preparation of dust suppression agent solution：According to mass fraction meter, 1 part of dust suppressant is added in the water of 5-10 parts, it is fully molten
Xie Hou, it is standby；
The sprinkling standard of dust suppression agent solution：By the dust suppression agent solution prepared according to 1.5-3.0kg/m2Standard be sprayed at
On ramp；
The spray method of dust suppression agent solution：Using mobile spray appliance, with single bridge truck distribution reservoir, connection high pressure sprinkling is set
It is standby, first pass sprinkling is carried out, after 5~8 hours, when dust suppression agent solution is completely penetrated under ramp surface, then is carried out
Second time sprinkling, by observation, when dust suppression agent solution is penetrated under ramp surface substantially after 12~14 hours, carry out the 3rd time
Sprinkling, when dust suppression agent solution completely penetrates 2~5mm under ramp surface, and when ramp surface conjunctiva is complete, ramp
Can normal use；During ramp normal use, need to be sprinkled water once daily, watering standard is 0.5-1.0kg/m2。
Moreover, the preparation of the dust suppression agent solution：According to mass fraction meter, 1 part of dust suppressant is added in 7 parts of water,
It is standby fully after dissolving；
The sprinkling standard of the dust suppression agent solution：By the dust suppression agent solution prepared according to 2.4kg/m2Standard be sprayed at
On ramp；
The spray method of the dust suppression agent solution：Using mobile spray appliance, with single bridge truck distribution reservoir, high pressure spray is connected
Equipment is spilt, first pass sprinkling is carried out, after 6 hours, when dust suppression agent solution is completely penetrated under ramp surface, then carries out
Second time sprinkling, by observation, when dust suppression agent solution is penetrated under ramp surface substantially after 13 hours, carry out the 3rd time spray
Spill, when dust suppression agent solution completely penetrates 4mm under ramp surface, and when ramp surface conjunctiva is complete, ramp can be just
Often use；During ramp normal use, need to be sprinkled water once daily, watering standard is 0.8kg/m2。
Moreover, the dust suppressant is environment-friendly degradable type dust suppressant.
Beneficial effects of the present invention：
1st, the present invention take the lead at home Underground Metallic Mines introduce Novel environment-friendlymaterial material dust suppressant, ramp spray environmental protection
Degradable dust suppressant, this environment-friendly degradable type dust suppressant have the characteristics that nontoxic, harmless, fully biodegradable, after use not
Secondary pollution can be formed, environment-friendly degradable type dust suppressant dust suppressant also has water suction moisturizing in addition to having consolidation, wetting, coalescence function
Function, i.e., the moisture when humidity is higher in (relative humidity is more than 30%) energy absorption air, while there is anti-rolling property, even if
In the case that cover layer is grinded up destroying, and road surface is dried, still with good dust suppression performance of keeping humidity.
2nd, the inventive method dust-laying effect is obvious, and in the case of daily watering once, watering standard is 0.5-1.0kg/
m2, air humidity 25-30%, moisturizing can be continued more than 60 days, watering number can not still be met by original daily 3-5 times will
Ask, daily watering till now once, just can be by environment dust concentration by original 48.5-57.3mg/m3It is reduced to 1.8-3.8mg/
m3, water saving and anti-dust effect are clearly；In addition, also save substantial amounts of artificial and vehicle abrasion cost, especially air ambient
In dust content have significant decline, improve underground labour working environment effect clearly.
