Description
Technical field
The invention belongs to mining technique field more particularly to a kind of sinking and drifting methods on loose crushing rock mass.
Background technology
In mining construction operation, with the driving in tunnel, construction personnel needs to face and pass through many address knots
The rock mass location of structure complexity, especially when passing through unknown loose crushing band, rock mass has the characteristics such as loose, broken, and country rock is made to hold
Easily there is avalanche inbreak phenomenon, on construction safety influence it is very big, in the prior art, generally require using method for protecting support to country rock into
Row could continue to carry out digging operation to tunnel after reinforcing, however, payment construction needs to expend a large amount of human and material resources, not only
It is with high costs, also make the construction period have to extend, restricts the promotion of construction efficiency.
Invention content
In order to solve the above technical problems, the sinking and drifting method that the present invention provides a kind of on loose crushing rock mass.
The present invention is achieved by the following technical programs.
The present invention provides a kind of sinking and drifting method on loose crushing rock mass, mainly includes the following steps that：
Step 1：Digging tunnel is excavated out on loose crushing rock mass according to certain cyclic advance scale；
Step 2：In the interval of cyclic advance digging construction, to the digging roadway surrounding rock that has been excavated out described in step 1 into
Row observation, finds out the rock stratum being caving completely in Rock Mass as Collapsed zone；
Step 3：Adit is excavated out on excavating out rock mass adjoining on the outside of digging tunnel；
Step 4：Drilled out in the adit excavated out described in step 3 be connected to Collapsed zone described in step 2 it is defeated
Send hole；
Step 5：The installation conveying pumping plant in the adit excavated out, by sprocket hole described in step 4 to described
The appropriate filler material of filling in Collapsed zone；
Step 6：After filler material solidification described in step 5, continue in pine according to the digging footage scale described in step 1
It dissipates and excavates digging tunnel on fragmented rock body.
Filler material described in step 5 is the concrete that label grade is less than 300.
It is pressure-increasing unit pumping plant that pumping plant is conveyed described in step 5.
By sprocket hole to further including when described the step of filling appropriate filler material inside the Collapsed zone described in step 5
Filler material shuts down conveying pumping plant when being overflowed from digging roadway surrounding rock rock mass.
The adit is mutually parallel with digging tunnel excavation direction.
The adit is arranged in above the Collapsed zone side.
Digging footage scale described in step 1 or step 6 is 1 meter.
The beneficial effects of the present invention are：Technical solution using the present invention is emitted by adit into digging tunnel
Interior concrete perfusion of settling in an area enables Rock Mass in digging tunnel to reinforce, effectively improves tunnel and adopt after concrete setting
Construction operation safety is dug, reduces the process that supporting construction operation is carried out to roadway surrounding rock, saves a large amount of supporting construction institutes
The human and material resources needed, reduce construction cost, shorten the construction period, improve digging construction efficiency, in addition, using smaller
Single digging footage scale be also beneficial to make the roadway surrounding rock rock mass internal stress of loose crushing in the single tunneling construction period
The state for inside keeing relative stability and balancing avoids the occurrence of the safety accidents such as Rock Mass inbreak.
Description of the drawings
Fig. 1 is digging tunnel of the present invention and adit position schematic diagram.
In figure：1- adits, 2- sprocket holes, 3- Collapsed zones, 4- diggings tunnel.
Specific implementation mode
Be described further below technical scheme of the present invention, but claimed range be not limited to it is described.
As shown in Figure 1, the present invention provides a kind of sinking and drifting method on loose crushing rock mass, include the following steps：
Step 1：Digging tunnel 4 is excavated out on loose crushing rock mass according to certain cyclic advance scale, further
Ground, digging footage scale are 1 meter.Technical solution using the present invention, the smaller single digging footage scale of use are also beneficial to
The state for making the roadway surrounding rock rock mass internal stress of loose crushing keep relative stability and balance within the single tunneling construction period,
Avoid the occurrence of the safety accidents such as Rock Mass inbreak.
Step 2：In the interval of cyclic advance digging construction, 4 country rock of digging tunnel that step 1 has been excavated out is seen
It surveys, finds out the rock stratum being caving completely in Rock Mass as Collapsed zone 3；
Step 3：Adit 1 is excavated out on excavating out the adjoining rock mass in 4 outside of digging tunnel；Further,
Adit 1 is mutually parallel with 4 excavation direction of digging tunnel, and adit 1 is arranged in above 3 side of Collapsed zone.Using the present invention
Technical solution, keep adit 1 adjacent with 4 position of digging tunnel, be conducive to shorten 2 length of sprocket hole, reduction construction
Duration improves construction efficiency.
Step 4：The sprocket hole 2 being connected to step 2 Collapsed zone 3 is drilled out in the adit 1 that step 3 has been excavated out；
Step 5：The installation conveying pumping plant in the adit 1 excavated out, by step 4 sprocket hole 2 to Collapsed zone 3
The interior appropriate filler material of filling, conveying pumping plant is shut down when filler material is overflowed from 4 Rock Mass of digging tunnel.Further, it fills out
Charge is the concrete that label grade is less than 300, and conveying pumping plant is pressure-increasing unit pumping plant.By pressure-increasing unit pumping plant, contribute to
Apply certain pressure into Collapsed zone 3, to offset part Rock Mass internal stress, Rock Mass internal stress is made to keep phase
To balance, working security ensure that.
Step 6：After the solidification of step 5 filler material, continue in loose crushing rock according to the digging footage scale of step 1
Digging tunnel 4 is excavated on body.Further, digging footage scale is 1 meter.
Technical solution using the present invention, by adit into digging tunnel concrete perfusion in Collapsed zone, wait mixing
After solidifying soil solidification, so that Rock Mass in digging tunnel is reinforced, effectively improve tunnel digging construction operation safety, reduce
To the process that roadway surrounding rock carries out supporting construction operation, the human and material resources needed for a large amount of supporting constructions are saved, reduces and apply
Work cost, shortens the construction period, improves digging construction efficiency, in addition, also being had using smaller single digging footage scale
It keeps relative stability and balances within the single tunneling construction period conducive to the roadway surrounding rock rock mass internal stress of loose crushing is made
State avoids the occurrence of the safety accidents such as Rock Mass inbreak.
