Study On The Whole Lift Transportation System Of Self-Driving Motorlorry In Deep Open Pit Mines

In order to tackle the key problems in present mining condition and transportation system in domestic deep open pit mines, study on the whole lift transportation system of self-driving motorlorry in deep open pit mines, which is key technology in highly efficient and deep transportation system, is made systematically. Through systematic analysis, it is concluded that one way to improve deep open pit mines transportation efficiency is to modify the lifting manner of the transportation system.By analyzing the structure, principle and applicability of the typical external driven wind whole motorlorry lift transportation system, self-driven automotive and wind whole motorlorry lift transportation system and self-driven automotive whole motorlorry lift transportation system, it is concluded that under such condition as there is no external wind lift, it is the wisest to establish self-driven automotive whole motorlorry lift transportation system, with the driving force of the lifted automobile as the lifting force. In addition, a new idea is proposed: automotive driving wheel connecting climbing gear whole gear whole motorlorry lift transportation system.From the perspective of technology and marketing management, the most outstanding advantage of the system is that it uses merely the driving force of the automobile itself to lift the heavy automobiles from minebottom up to the surface along slope lifting paths, rather than using auxiliary power. Its features are as follows: 1. slope lifting paths extend accordingly with the deepening mining field; and transportation distance shortens lineally, and they remain the same during the entire mining period. 2. it helps to develop new mobile mine paths, mine slope side, and reduce the total amount of rock peeling within field.3. it helps to leave out the transition in the joint transportation system in the mining field, thus reduces the cost of construction to a large degree. 4. last but not the least, the current technology can insure the manufacturing and carry-out of the system.Based on the principle of applicable technology, reliability and safety and sensible economic consideration, and by means of qualitative and quantitative analysis, it is believed automotive driving wheel connecting climbing gear whole motorlorry lift transportation system is technologically applicable and the system is safe and sound.In the sense of investment and transportation cost, the applicability and economic sensibility of the basic plot of automotive driving wheel connecting climbing gear whole motorlorry lift transportation system has been investigated. It is believed that the self-driven whole motorlorry lift transportation system costs less in investment and transportation than regular automobile transportation systems, and that it enjoys advanced technology, saves money and protects the environment. The system increases profit for domestic deep pit open mines, extends their life span and has a good reason to be widely used.
