A major improvement in the efficiency of production is now due to breakthroughs in science and technology, tools and leaps, such as the fact that in the past we had been able to drill only artificially, but now, because of the emergence of a rock-scrawler, we can achieve the desired results with ease. There are many other classifications on the market, including the yt28-type gas-leg-diggers, which perform well and use the most reliable machines, and which are widely used in the drilling of the alleys and in various types of drilling。
I. Rationale for the work of the rock-mining machines
It works on the basis of shock fragmentation. Pistols are used for high-frequency back-to-back movements while they work and keep hitting tails. Under the effect of the shock, a wedge-like head crushes the rock and digs into a certain depth to form a dent. When the piston returns, the piston turns to a certain angle, and the piston moves forward and hits its tail again, forming a new dent. The sectoral blocks between the two dents were shredded by horizontal fracturing from the head of the poach. Pistols keep impacting on the tails of the pistons and continuously entering compressed air or pressure water from the central hole of the piping, excavating the slag out of the hole, i. E. Forming a circular drill at a certain depth
Ii. Cracker yt28
The yt28-type gas-leg-digger is the most modern rock-digger product, using modern design techniques that are efficient, low noise, light weight, good economic performance, speed of progress, etc. It is superior in its performance and most reliable in its use. The most efficient stoner. It is best suited for large-scale mining, medium-sized mining and swirling operations, with the best reaction from domestic users, with over 70 per cent of the north korean market
Iii. Protocol for the operation of the rock-cracker
1. Check the integrity and rotation of the various components (including the screechers, scaffolds or screechers) before drilling, with the necessary lubricating oil, checking the windways, whether the waterways are open and whether the connections are strong。
2. A knock on the top near the workspace, i. E. A check on the ceiling near the workspace and on the presence of live stones, pinestones, #formatimgid 0# inner screechers and necessary handling。
3. The position of the working surface eye will need to be levelled in advance before the rock can be drilled to prevent slippage or diversion。
4. Dry eyes are strictly forbidden, and wet rock drilling is maintained, with the operation being carried out with the opening of the water, followed by the opening of the wind and the closing of the drill with the closing of the wind and the closing of the water. The eyes are opened at a low speed and only when they reach a certain depth before full speed。
Five. No gloves for the helpers during the drill。
6. When using air legs to drill in the eye, be careful to stand and position, and must not rely on physical pressure, let alone stand under a pole in front of a rock-digger, in order to prevent injury from being broken。
7. When an abnormal sound is found in the rock, when the discharge water is abnormal, it should be stopped to find out the reasons and remove them before further drilling。
8. When exiting or replacing quarries, they can operate at a slow pace, paying careful attention to the position of the quarries, avoiding the automatic removal of the quarries and the timely closure of airways。
9. When using an air-legging machine to drill rocks, the top is to be firmly held to prevent the top being sliding。
10. When using an uplifting rig, hold the pole in case the pole automatically falls。
We have learned that the work of a rock-scrawling machine is based on the crushing of rocks through shocks, followed by openings, which not only result in significant savings in human costs, but also in ease of operation and low noise, so that the role played in the drilling of caves and other similar large, medium-sized ore mines and tunnels is also crucial. When we choose, we need to refer to the classification under the flag
