Description
Technical field：
The utility model belongs to the Mine Shaft Lining in mine vertical construction technique field more particularly to poor strata and applies
Frock is put.
Background technology
Vertical is important promotion, ventilation, transport, draining and the personnel safety passage of underground mining contact underground and earth's surface,
Pit shaft is connected directly with earth's surface, is directly born pit shaft and is promoted the whole load of facility, for that purpose it is necessary to ensure that shaft of vertical well structure has
There are enough bearing capacities and non-deformability.
With the rapid development of mining industry, the ratio shared by underground mining is increasing, and vertical is increasingly deeper, the ground that passes through
Layer becomes increasingly complex, and especially shaft of vertical well rock section is in bad water-bearing layer as severely-weathered layer, middle weathered layer and water-enriched layer,
In, severely-weathered layer and middle weathered layer belong to aquitard, and cranny development degree has differences, and lower part is strong aquifer.It is bad to contain
Water layer protolith ingredient based on tufaceous, by it is severely-weathered effect it is changeable turn to the clay minerals such as kaolin, in loose earthy or be in
Relic shape is shown in air or meets water and then disintegrate in fluffy that crack is permeable, and water yield is big, and pit shaft can not descend pick, supporting.
Now, the conventional method that shaft of vertical well rock section is in bad water-bearing layer is freezing or shaft face slip casting
Method.Freezing is to bore a circle or two circle freezing holes to rock stratum or wellbore bottom 10m~20m is stablized from earth's surface, in freezing hole entirely
Hole, which is set, freezes steel pipe, refrigeration station is arranged in earth's surface, by freezing steel pipe by refrigerating fluid circulation conveying to freezing hole bottom, so as to reach
To freezing shaft whole body country rock, achieve the purpose that water-impervious reinforces country rock.Existing defects are this method refrigeration system equipment durations
Long, cost height, power consumption are big.Shaft face slip casting method, be shaft face soon close to bad water-bearing layer when, stop driving,
10m or so is stayed to stop, and magmatic rock emits or casting concrete grout cover, the arrangement drilling in shaft face carry out grouting.It deposits
It is that the slip casting pump power that this method uses is small, and slip casting ability is low in defect, injecting paste material consumption is few, it is difficult to block crack passage
In water, after Shaft Excavation, water yield is still very big, and crack water burst drives wall damage, causes disaster.Practice have shown that this two
The kind equal existing defects of method, can not meet the requirement of self well digging and bearing capacity.Therefore, a kind of more rational rock section is sought
Bad water-bearing layer positioning targeting slip casting Mine Shaft Lining and construction method are extremely urgent.
