Description
Technical Field
The invention relates to the technical field of coal industry, in particular to a self-moving disaster isolation gate wall.
Background
Currently, five natural disasters of coal mines refer to: flood, fire, gas explosion, coal dust, roof accident.
1. Flood disaster
A large amount of flood engulfs the tunnel in a very rapid time, causing the death of the crew. Normally, the survivors cannot rescue, remains cannot be recovered, and the tunnels are abandoned as well. In the coal mining on the pressure-bearing water and the repeated mining in the small coal kiln damage area, water burst and water permeability accidents can also occur. The underground water burst and small coal kiln water penetration accidents are far more than the underground coal mining water penetration accidents.
2. Fire disaster
Worst case in coal mine accidents. Unlike a general fire, many combustibles (coals) exist around in large quantities. If the tunnel is blocked by heat and smoke and hypoxia occurs at the same time, serious injury and death usually occur.
3. Gas explosion
Often accompanied by the presence of gas (methane, etc.) in the coal seam. The gas is liable to cause explosion accidents. Thus, when working in closed spaces, it is necessary to constantly monitor the gas concentration. If dust exists in the gas at a certain concentration, explosion caused by sparks is also possible. The dust volume is small but the relative proportion of the surface is large. If there is sufficient oxygen in the ambient air, it is very sensitive to the combustion reaction. The gas itself is harmless to the human body, but sometimes accompanied by toxic gases such as carbon monoxide. If a large amount of gas is ejected at a time, the possibility of explosion of the gas generally increases rapidly.
4. Coal dust
If dust exists in the gas at a certain concentration, explosion may be caused by sparks. The dust volume is small but the relative proportion of the surface is large. If there is sufficient oxygen in the ambient air, it is very sensitive to the combustion reaction.
5. Roof accident
With the exploitation of the working face, the roof strata on the coal bed lose support, the original pressure balance is destroyed, and the roof of the coal bed is deformed and destroyed under the action of the overlying strata pressure. If the support is not timely or the support strength is insufficient, the roof strata of the working surface are easily broken and fall, so that casualties, property and equipment are lost, and the roof fall accident is what we say.

It can be appreciated that the self-moving disaster isolation gate wall is arranged between the hundred-meter danger-relieving area and the normal working area, and can continuously move forward along with the pushing of the tunneling working face.
The distance between the setting position of the self-moving disaster isolation gate wall and the tunneling head of the tunneling machine is 50-100m. Mainly has two functions: firstly, physical isolation is carried out on disasters at the moment of occurrence, so that the safety of operators in a roadway beyond hundred meters is ensured; second, disaster buffering is carried out, and sufficient escape time is provided for operators in the roadway to escape. Preferably, the number of the self-moving disaster isolation gate walls is one, and of course, a person skilled in the art can set the number of the self-moving disaster isolation gate walls into a plurality according to actual needs, and the plurality of the self-moving disaster isolation gate walls can be linked and can also be controlled independently.
In this embodiment, the self-moving disaster isolation gate wall is provided with an upper gate 1 and a lower gate 3, which can be controlled separately. The upper gate 1 can be correspondingly matched with an escape and transportation system, and the escape and transportation system is movably arranged between the hundred-meter danger-relieving area and the normal working area and is used for assisting material transportation and personnel evacuation.

For example: the self-moving guide rail is arranged at the bottom of the roadway. The self-moving guide rail includes: the guide rail and the sliding block arranged on the guide rail are connected with the gate wall body. Of course, the driving mode of the sliding block can adopt a common mode that the sliding block is driven by a motor through screw rod transmission, and other modes can also be adopted. In addition, the self-moving guide rail can be arranged at the top of the roadway, and is similar to hoisting at the top of the roadway. Of course, no matter how set, a point should be satisfied to not interfere with the normal operation of the downhole equipment.

In addition, for the inflatable body, a bag structure can be used, and sealing with the rock wall is achieved by incorporating a water-swellable material in the resilient bag. Of course, an automatic water spraying device can be added for adding water to the elastic bag. In addition, even with the balloon structure, the sealing with the rock wall can be achieved by ventilation and expansion. Of course, an automatic air supply device can be added for air filling into the air bag structure. The three sets of technologies can be used singly or in any combination.
For the self-moving disaster isolation gate wall, the self-moving disaster isolation gate wall can be linked with a tunneling shield support, and can keep the same distance with the tunneling shield support at any time.
For example: the self-moving disaster isolation gate wall is provided with a first sensing element, the tunnel tunneling shield support is provided with a second sensing element, the first sensing element and the second sensing element are mutually sensed to determine the distance between the first sensing element and the second sensing element, and then the distance is fed back to the control mechanism to control the self-moving disaster isolation gate wall to move. Of course, the time interval type disaster isolation gate wall can be set empirically, and the self-moving disaster isolation gate wall can be automatically moved when a preset time is reached.
The tunnel excavation shield support specifically comprises: the shield plate beam is provided with a bidirectional ejection mechanism which can simultaneously eject above and below the shield plate beam, and the bidirectional ejection mechanism is propped against a roadway bottom plate and a roadway top plate, so that the shield plate beam is supported at a set height below the roadway top plate.

Further, a plurality of bi-directional jacking mechanisms are arranged on the shield beam, and the shield beam is lifted to a set height by controlling the extension length of each bi-directional jacking mechanism above and below the shield beam. The tunnel roof or tunnel bottom plate is rugged, and the shield beam plate is kept at the set levelness by controlling the extension of each bidirectional extension mechanism to different lengths, so that torque damage is avoided.

Further, the upper piston cylinder and the lower piston cylinder are disposed along the same axis. And the damage caused by resultant torque generated by the action of two piston cylinders on the shield beam in the bidirectional ejection mechanism is avoided. Further, the upper piston cylinder and the lower piston cylinder are arranged in a staggered manner, so that the axes of the upper piston cylinder and the lower piston cylinder are parallel. The resultant moment on the shield beam is required to be guaranteed to be zero. Further, a bearing cross beam is arranged, the lower piston cylinder positioned on the same side is arranged on the lower side of the bearing cross beam, and the upper piston cylinder is arranged on the upper side of the bearing cross beam. Further, a drilling skylight is arranged on the shield plate beam. The anchor rod (rope) drilling equipment is used for drilling holes in the top of a roadway through a drilling skylight and is used for installing the anchor rod (rope).
Further, the shield beam is provided with a mounting hole of the bidirectional ejection mechanism. Further, the bidirectional propping mechanisms are arranged on two sides of the shield beam, and the distance between the bidirectional propping mechanisms on two sides is larger than the width of the heading machine. Interference between the heading machine and the bidirectional ejection mechanism is avoided. Further, a bearing mechanism for bearing the shield support to move back and forth along the roadway is arranged on the heading machine. The clamping device can fix the shield support on the tunneling machine, so that the shield support moves along with the tunneling machine in a roadway, and the tunneling machine conveys the shield support to a temporary support area. Further, a movable driving mechanism for driving the shield support to move along the extending direction of the roadway is arranged on the shield support. The mobile driving mechanism can enable the shield support to move in the roadway by itself, and the shield support is conveyed to the temporary support area by the mobile driving mechanism. Furthermore, the shield plate beams are of an integrated structure or a spliced structure, and the shield plate beams of the spliced structure are of concave-convex splice plates and are connected into a whole through high-strength bolts.
