in the year of graation, I came to the coal mine and was assigned to the excavation team to work in three shifts, including blasting, mechanical excavation, anchoring, and carrying cement sleepers and single pillars. All the work of the excavation team was heavy manual work, which was very hard. Especially when I was on the night shift, I could fall asleep standing up, and I didn't have autumn clothes and trousers on my body, I don't even have the strength to take chopsticks when I eat after work, so I can fall asleep when I fall into bed. It's hard to work hard in the mine for a year, but it can also train people. What I thought at that time was that as long as I wasn't tired to death, I would go on working
in the second year, I was assigned to the ground machine repair workshop to do mechanical repair work, such as lathe, welding, recer, coupler, roadheader, shearer, pumping station, belt conveyor, winch, etc. anyway, the underground mechanical equipment was almost repaired. I learned a lot in this year. I took notes while repairing things, and then read the books when I went to school after work, If you work harder, you can undertake the repair work independently in a year
in the first half of the third year, I was assigned to work as a mechanical repairman in the fully mechanized mining team. In retrospect, that time was the most pleasant time for me, because the repairman in the fully mechanized mining team was a technical type of work. As long as the fully mechanized mining equipment was normal, the leader almost didn't care, especially free, and if there was no problem, I would get out of the well ahead of time. However, one thing is that the mobile phone must be turned on 24 hours a day. As soon as the equipment breaks down, it has to go down to repair the equipment in the middle of the night. There are almost no weekends, because when others rest, you have to go down the well to repair the responsible equipment
in the second half of the third year, I was assigned to work as an electrician in the mechanical and electrical team. From the beginning of my apprenticeship, I always felt that it was much easier to work as an electrician than a repairman. After three months of study, I was on ty independently, because the principle of coal mine electrical equipment was much simpler than that of school. As long as I went to school, some electrical skills were easy to master, and then I dealt with several rare faults independently, Almost able to cope with the electrical operation of the coal mine.
it is strongly not recommended to use the mining machine, if possible, it is best to directly go to the high mining area

2. The maximum lump size of ore feeding should not exceed 80-85% of the width of ore feeding mouth
3. The adjusting gap of the ore outlet should be within the range of 100-160 mm (the crushing cone is 1:3, that is, the crushing cone rises by 6 mm and the ore outlet decreases by 1 mm)
4. It is strictly forbidden for metal iron and other foreign matters to enter the crusher cavity ring operation. If they enter, they should be stopped immediately for elimination. 1. Check whether there is enough lubricating oil in the oil tank, whether the oil quality meets the requirements, and whether the oil filter is not clean

7. If there are any materials in the crusher chamber, it must be removed before starting
8. Whether the easily worn parts of the engine body (such as broken cone liner and middle frame liner) are seriously worn or cracked
9. Check whether the funnel is blocked or seriously worn
10. Check whether the hand wheel of oil immersed rheostat in electrical part is at zero position
11. Check the contact condition of motor carbon brush
12. It is not flexible to check the distribution box and operating mechanism
13. Check whether the pointer of ammeter is at zero. 1. Operation method of the equipment
(1) before operation, the equipment must be inspected item by item according to the inspection content
(2) start the oil pump first, and start the motor only after the return oil is normal
(3) pay special attention to the sound of motor and crusher when starting, and stop running immediately in case of any abnormality
(4) start feeding after normal operation of the equipment
(5) ore feeding must be stopped when the operation is stopped, and it can only be stopped when there is no ore in the crushing chamber
(6) stop the oil pump feeding
2. Start up operation sequence:
(1) first check whether the oil immersed rheostat is at the zero position and whether the short-circuit switch is open
(2) press the start button
(3) slowly transfer the hand wheel of the oil immersed rheostat to the starting position until the motor reaches the rated speed
(4) close the short circuit breaker
(5) observe whether the indication of ammeter is normal
(6) the motor shall not be started frequently, and generally it shall not be started more than three times continuously
3. Stop operation sequence:
(1) stop feeding before stop, and stop the crusher when all ores in the crusher cavity are discharged
(2) the operator presses the stop button
(3) turn the hand wheel of the oil immersed rheostat back to the zero position and open the short-circuit knife switch
(4) after power failure without notice or shutdown with load, the ore in the crusher cavity must be taken out to facilitate the start-up after power supply
