Abstract
The invention provides a tunneling method for a coal mine strike type high suction tunnel, belonging to the technical field of down hole rock tunnel excavation equipment and aiming at providing a tunneling method for a coal mine strike type high suction tunnel; the tunneling method utilizes small-sized TBM (tunnel boring machine) equipment for excavation and is high in security and fast in speed; the technical scheme adopted for solving the technical problem is that the tunneling machine is manipulated to swerve by controlling a walking cylinder at one side of the tunneling machine to elongate and controlling a walking cylinder at the other side to shorten; the tunneling machine swerves and enters the space above a second working plane boring hole and excavates the high suction tunnel till the upper part of a return air large tunnel; the tunneling machine is manipulated to swerve by controlling the walking cylinder at one side of tunneling machine to elongate and controlling the walking cylinder at the other side to shorten; and the tunneling machine swerves and enters the space above a third return air large tunnel and excavates the high suction tunnel till the upper part of the boring hole. The tunneling method can be used in coal wells widely.
Description
Technical field
The present invention moves towards the driving method that the type height is taken out the lane in a kind of colliery, belongs to down-hole rock gangway excavation equipment technical field.
Background technology
The type height of trend is taken out the lane, is arranged in top, coal seam top board fissure zone, and tunnel length is close with the work plane strike length, and section size 4 ~ 6 ㎡ get final product, and afterbody links to each other with the big lane of return air.Existing driving method mainly contains two kinds, and a kind of is traditional drilling and blasting method, promptly drills and blasts, and installs to the rock ballast of blowing on the mine car then or clears up on the drag conveyor; Another kind is to adopt boom-type roadheader, carries out the partial cut rock mass, then rock ballast is transported on the supporting belt in back; These two kinds of methods all can not disposable one-tenth lane, can not realize digging the anchor one, tunnels 1 to 2 meter forward, just need stop and carry out supporting, and safety is not high, restricts speed of application simultaneously, influences coal mine excavation and is connected.
Summary of the invention
The present invention has overcome the deficiency that prior art exists, and provides a kind of safe, fireballing colliery that utilizes small-sized TBM equipment to excavate to move towards the driving method that the type height is taken out the lane.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopts is: the driving method that the type height is taken out the lane is moved towards in a kind of colliery, carries out according to following steps:
The first step: development machine is reached in the big lane of return air;
Second step: development machine excavates the mined bed top because the fissure zone that mining influence forms excavates along the fissure zone level and cuts the eye top from the big lane of return air to oblique upper earlier;
The 3rd step: through the walking oil cylinder elongation of a side on the control development machine, the walking oil cylinder of opposite side shortens handles the development machine turning;
The 4th step: development machine is cut the top of eye through second work plane of entering of turning and is excavated its height and take out top, the big lane of lane to return air;
The 5th step: through the walking oil cylinder elongation of a side on the control development machine, the walking oil cylinder of opposite side shortens handles the development machine turning;
The 6th step: development machine through turn getting into the big lane of return air, the 3rd work plane place the top and excavate its height and take out the lane and cut the eye top to it;
The 7th step: repeated for the 3rd step and the 6th step, excavate the height of all working face successively and take out the lane;
The 8th step: the height of second work plane and back all working face is taken out the lane all dig through with the big lane of return air;
Described development machine is TBM, i.e. tunnel machine.
The beneficial effect that the present invention compared with prior art has is: the present invention utilizes small-sized TBM equipment in height is taken out the lane, to tunnel forward; And the height that continues to excavate next work plane of turning is taken out the lane; Realized pick anchor one, safe, and improved drivage efficiency.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further explanation.
Fig. 1 is the high position view in lane of taking out among the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the sketch map of development machine track route among the present invention.
Among the figure, 1 takes out lane, 5 for fortune lane, 4 for height and is the big lane of return air for cutting eye, 3 for air way, 2.
The specific embodiment
Like Fig. 1-shown in Figure 3, the present invention moves towards the driving method that the type height is taken out the lane in a kind of colliery, carries out according to following steps:
The first step: development machine is reached in the big lane 5 of return air;
Second step: development machine excavates the mined bed top because the fissure zone that mining influence forms excavates along the fissure zone level and cuts eye 2 tops from the big lane 5 of return air to oblique upper earlier;
The 3rd step: through the walking oil cylinder elongation of a side on the control development machine, the walking oil cylinder of opposite side shortens handles the development machine turning;
The 4th step: development machine is cut the top of eye 2 through second work plane of entering of turning and is excavated its height and take out 5 tops, the big lane of lane 4 to return air;
The 5th step: through the walking oil cylinder elongation of a side on the control development machine, the walking oil cylinder of opposite side shortens handles the development machine turning;
The 6th step: development machine through turn getting into the big lane 5 of return air, the 3rd work plane place the top and excavate its height and take out lane 4 and cut eye 2 tops to it;
The 7th step: repeated for the 3rd step and the 6th step, excavate the height of all working face successively and take out lane 4;
The 8th step: the height of second work plane and back all working face is taken out lane 4 all dig through with the big lane 5 of return air;
Described development machine is TBM, i.e. tunnel machine.
