1, adopt emergency measures after the coal face roof fall occurred
1) Rapid evacuation.
2) Avoid in time.
3) Call for help immediately.
4) Cooperate with rescue.
2. Emergency measures for the person who is blocked by the top of the road
1) Face the situation and calmly cope.
2) Do everything possible and seek relief.
3) Maintain the living conditions of the trapped location.
3. Method for rescuing people in distress after a roof accident occurs at the coal mining face
1) Suspend power supply to electromechanical equipment near the landing zone.
2) Check and maintain the safety of the landing site and its vicinity (whether the support is firm? Is there any gas escaping? Is there any danger of falling again?) to ensure the safety of the rescue personnel during the disaster relief, and there is smooth, Safe retreat.
3) When the range of the fall is not large, if the person in distress is pressed by the large piece of meteorite, the large rock can be supported by tools such as hydraulic jacks, and the person in distress can be rescued.
4) If the top plate falls along the coal wall, the rock mass is relatively broken. When the person in distress is close to the coal wall position, a small hole can be made from the outer roof to the inner wall along the coal wall. (If the person in distress is close to the topping area, then The trapping shed is set up from the outside to the inside of the cave. (The gangs of the landscaping area must be backed with wooden boards to prevent leakage of ochre). The side walls are supported and the rescued personnel are rescued.
5) Slicing Face Roof occurs, a seam floor, the position of the persons in distress or the genus Vitex leave the top web beneath the gold, can dig holes along the bottom seam, side support hole Cutting edge, close to the persons in distress after It was rescued.
6) If the bottom plate is rock, when the position of the insurer is below the metal net or the false roof, you can approach the distressed person along the small hole in the coal wall, and then take measures according to the situation (such as using a wind to smash a small hole in the bottom plate) Etc.) Arrive at the person in distress and rescue him.
7) If the working face and the lower exit fall at the same time, or the middle of the working face has a large range of falling, and the person is blocked in the middle, when the small hole is long and unsafe, the method of re-opening the eye along the coal seam can be used. And save people.
4. Rescue method for the blocked personnel after a large area of ​​roofing occurred in the heading face
1) Suspend the power supply of electromechanical equipment near the roof area.
2) Use fresh air, water and food to the location of the person to be separated by means of air ducts, water pipes and drilling.
3) According to the location of the person in danger of being blocked, it is determined to use the method of restoring the fallen roadway or bypassing to reach the disaster-stricken place for the rescue.

Process
The sheet is processed in the following steps: decoil the raw material, feed with a fixed length via the servo motor, shearing it with various shearing tools into sheets of various types according to the drawing and then piling them on the stacking table via the conveying mechanism and the arranging mechanism.
Functional features:
1. This device can complete automatic production of various sheets for laminated, Full tapered seam cores.
2. Shearing power: imported electrical servo control technology is adopted, so the device is featured by high speed, low noise and long life.
3. Feeding power: adopt high torque AC synchronous servo motor, so has characteristics such as rapid response, high positioning and accuracy, low noise, low braking thermal loss and long life.
4. Track positioning: the centralized positioning is achieved by dragging the linear tracks of the ball screw with a servo motor. So the positioning is rapid, accurate and convenient and the track width can be memorized automatically.
5. Movement control: advanced PCC control and ethernet powerlink communication technology is adopted, reducing greatly wiring and imporving the reliability, stability and real time of the system remote control and trouble diagnosis can be achieved via the above control and technology, shortening the maintenance time and reducing the cost to the largest extent.
6. Arrangement mode: the backward pushing arrangement mde is adopted and long sheets can be arranged orderly with low vibration, reducing the orientational permeance of the processing process on silicon steel sheets to the largest extent.
7. Life guarantee: standard components of the device are imported quality ones. High accuracy of processing and assembly of basic components extents the service life of the device to the largest extent.
8. This device is a high techmechanical, optical and electrical integrated product with multiple patented technologies, it represents high manufacture level of domestic transverse shear lines and can substitute imported products, saving much outsourcing fund. Some models have automatic cut in cut become column functions.
