The main measures to improve the efficiency of power transmission are:
1. Increase the bucket volume. The increase in the volume of the bucket not only increases the amount of ore that is transported each time, but also increases the blockiness that allows for the transport, which is conducive to improving the efficiency of the transport. However, to increase the bucket volume, the winch power should be increased accordingly, so that the size and weight of the equipment are increased, and the required specifications of the roadway are also increased, which makes it difficult to install and relocate the power supply. Only in mines where the ore rock is relatively stable and the mine has a large amount of ore-mining, and the capacity of the electric raft is required to be large, it can be considered.
In the case of good ore crushing quality, double hopper series tantalum ore can also be considered. The three factories of Yimen Copper Mine generally use double 耙 耙 耙 mine, which can increase the capacity of electric raft transportation by about 50% .
2. Increase the bucket fullness factor. The degree of filling of the bucket depends on the structure of the bucket, the quality of the ore crushing, the distribution of the ore and the straightness of the mineway. Reasonable choice and design stope bottom structure, ensure quality and improve the quality of crushed ore to improve the technological levels of power rake work, it is to improve the fill factor of the harrow main aspects.
3. Improve the time of pure antimony ore. At present, the pure antimony mining time transported by eDonkey only accounts for 10~40% of the working hours of the class . Most of the time is spent on large blocks, handling funnel jams, equipment failures, waiting for mine cars and other artificial stops.
The main potential for improving the efficiency of power handling is to increase the time of pure operation.
Improving the quality of ore crushing, reducing the number of collapses and handling of the bucket is a major aspect of improving the operation time of the power plant. According to statistics, for every 5% increase in the block rate , the efficiency of electricity is almost reduced by half. Strengthening the maintenance of equipment, arranging the coordination of mining and stage transportation, and mobilizing the enthusiasm of electric power is also an important aspect to improve the working time.
4. Reasonable choice of transport distance. The transportation distance is inversely proportional to the production capacity of the electric power. In fact, due to the increase of the transportation distance, the illumination light is insufficient, and the full-scale operation of the bucket causes the filling factor to decrease, and the electric power worker cannot clearly see the electric power running. Increasing the number of accidents makes the efficiency of the embers easy to drop significantly.
In order to shorten the lay length, the mine can be increased under economic and reasonable conditions. Some mines are located between two mine pomegranate wells, close to 2/3 of the end of the electric winch , to the chute close to the winch, and the remaining 1/3 of the distance, to the other chute, The winch is not displaced, which also gives good results.
5. Under the conditions of the stability of the ore rock, increase the size of the ore roadway and the ore discharge port, which can improve the ore flow and reduce the fighting and arching.
6. Strengthen the maintenance of electric ramps, improve the ventilation, dustproof and lighting conditions of the electric ramp.
7. Strengthen the maintenance and overhaul of equipment to improve the integrity and utilization of equipment. Once the electric sampling mine is put into production, the continuity of production should be maintained as much as possible until the end of the mining, which is also an important condition for improving the production capacity of the stope.
What are the ways to improve the effect of eMule transport?
The production capacity of electricity is affected by many factors. The magnitude of the change is large, often several times the difference. For example, use 30kw, 0.3m3 Â Electric trick harrow, the current general Taiwan-Japan production capacity of 150 ~ 200t, but Zhongtiaoshan non-ferrous metals company Hujiayu copper ore, Taiwan and Japan in 1966, the average production capacity of 482t.
