2.Press the shearer stop button to stop the shearer and close the sprinkler shut-off valve.

Turn off the water, and then hit all the operating handlebars, including the isolation handlebar, clutch handlebar, to the "zero" position.

3.When off duty or during maintenance, the shearer should be parked in a safe and reliable place, and the drum should be dropped on the bottom plate to lock the scraper conveyor.

4.When the shearer stops cutting coal and gets off work, the driver should overhaul and clean up the floating coal on the shearer body according to the content before starting, so as to keep the shearer clean and tidy.

5.Downtime in exceptional circumstances.

1) In the following situations, use the shearer "Stop" button to stop.

a.Abnormal noise in the machine;

b.Cables, water pipes jammed or slotted.

2) Use the "Emergency Stop" button to stop in the following situations.

a.There are large pieces of gangue or wood and coal in the chute of the scraper conveyor of the mining face that will resist the shearer;

b.The cable and water pipe are hung by the conveyor;

c.The "stop" button of the shearer is out of order;

d.Other accidents.

6.Other. 1) It is forbidden to use shearers to pull and push other equipment.

2) To maintain electrical equipment, the safety regulations for underground electrical maintenance should be implemented.

3) When the shearer cuts to the upper and lower mouths, it is necessary to send out a signal, and set up a guard at 10m away from the coal gang on both lanes of the fan to prevent the coal from flying out and injuring pedestrians.

4) When the cover plate needs to be opened to eliminate the fault of the shearer, a shed cloth should be built above to prevent crushed gangue, crushed coal and other sundries from entering the oil pool.

7) As the shearer cuts coal, the bracket guard plate should be retracted in time 2-3 frames from the front drum.

8) Before the shearer stops each shift, the coal top of the upper oblique knife feed section should be cut together, so as to move the support of this section in place and support the roof.

9) When filling and overhauling the shearer drum, the shearer should be parked in the maintenance machine nest that has been reserved in advance, and the isolation switch handle and the reversing handle should be hit to the "zero" position. The scraper conveyor for locking work is carried out under the supervision of the roof and coal gang.

10) The driver should strictly control the height of the left and right drums, and cut the triangular coal at the head and tail of the machine.

Summary. Dear, hello, I am happy to answer for you, what should be paid attention to when cutting coal in the shearer: it is strictly forbidden to forcibly cut hard rock and start with load, run with disease, and maintain the shearer according to the standard.

What should be paid attention to when cutting coal in a shearer.

No need. Dear, hello, I am happy to answer for you, what should be paid attention to when cutting coal in the shearer: it is strictly forbidden to forcibly cut hard rock and start with load, run with disease, and maintain the shearer according to the standard of virtual high liquid.

Dear, hello, I am happy to answer for you, shearer coal cutting regulations: 1The shearer driver must be trained, master the structural principle of the shearer and the troubleshooting method, be familiar with the relevant regulations, and hold a certificate to work.

2.It is necessary to work closely with the working face slider driver and bracket worker to start and stop the machine in the prescribed order. 3.

It is forbidden to forcibly cut roof beams and hard rock. 2. Operation and precautions: 1

When arriving at the work site, you should carefully check whether the parts of the shearer are short of oil, whether the various buttons and handles are sensitive and reliable, whether the various protective equipment is complete and effective, and whether the picks are complete. 2.Before the shearer starts, the driver must patrol the area around the shearer, notify all personnel to evacuate to a safe place, and confirm that there are no personnel and obstacles within 5 meters of the upper and lower drums, and then start the shearer.

3.Get the permission of the squad leader to send a signal, the shearer first idles for 2 to 3 minutes, and the mechanical operation of each component is normal, and it can be officially started. 4.

With the shearer's permission and the shearer's permission, the shearer driver signaled and then slowly accelerated the traction to start the coal cutting operation. 5.When cutting coal, the driver should pay attention to the height of the upper and lower at any time to prevent cutting the metal mesh and cutting the coal plate.

In order to ensure that the working face is three straight and one flat, the undercover amount is controlled in meters, and the mining height is controlled in meters. 6.The shearer driver should stand in the support channel to operate the shearer, pay attention to the top and help situation at any time, and pay attention to the drum throwing coal or sheet coal hurting people.

7.When cutting coal, the non-unit driver should stay 5 meters away from the drum to prevent the drum from throwing coal and injuring people. 8.

When cutting coal, pay attention to the condition of the walking mechanism at any time, whether there are personnel and obstacles in front of the shearer, and whether there are large pieces of coal, gangue or other objects passing under the shearer. If an unsafe situation is found, stop pulling immediatelyand cutting, and locking the working face chute for processing. 9.

When the various button handlebars of the shearer fail, it must be stopped immediately for processing. 10.When it is necessary to stop for maintenance or have personnel to work on the working face of the lower part of the shearer, the double drum of the shearer must hit the ground, and at the same time open the clutch, disconnect the isolator and lock the working face chute; If it is necessary to shut down the operation for a long time, it is necessary to cut off the power supply of the shearer and the chute of the working face and lock it.

11.The co-driver who looks at the cable must make sure that the cable moves smoothly in the groove next to the cable section, and prohibits the cable from sliding outside the cable trough to prevent the cable from sliding quickly or being hung up. I hope this service can help you, thank you for your consultation, and I wish you all the best!

The working process of the shearer is:

At the same time that the left and right cutting drums rotate, the shearer moves to the left or right along the coal wall, the shearer keeps moving, the cutting drum rotates continuously, the coal is constantly cut off from the coal wall, falls on the scraper conveyor at the bottom of the shearer, the scraper conveyor transports the cut coal out, because the coal block cut by the cutting drum is sometimes too large, the scraper conveyor can not be transported, so there is a crushing drum on the shearer, which is used to crush the large coal mine. Due to the different thickness of the coal seams, it may be necessary to adjust the front and rear cutting rollers up or down in order to cut the coal seams of different thicknesses.

The working process of the shearer mentioned above is the main function that the shearer must have, and the shearer must provide mechanical power for it to complete these actions, and these powers are provided by the motor, so the action of the shearer is to control the rotation, speed change, reversal and stop process of the motor.

The shearer is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce manual labor, improve safety, and achieve the purpose of high yield, high efficiency and low consumption.

The shearer is divided into sawing, planing, drilling and milling: the shearer is a large-scale complex system integrating mechanical, electrical and hydraulic, the working environment is harsh, if the failure will lead to the interruption of the entire coal mining work, resulting in huge economic losses. With the development of the coal industry, the functions of the shearer are more and more, and its own structure and composition are more and more complex, so the reasons for the failure are also complex.

The double-drum shearer integrates the successful experience of thin coal seam shearers at home and abroad, and is a new type of high-power thin coal seam shearer designed for China's specific national conditions.
