The Completed Opencut Dump Truck Promotion Systematic Research And Analysis

This article introduces and analyzes the characteristics and development orientation that the domestic and international opencut exploits, which chiefly includes opencut equipment maximization, exploitation craft diversification and automation of mines' management and exploitation. This article also introduces the main means way in which the ground relying mainly on automobile transportation of opencut transports in detailA great deal of the mining practices have indicated that though opencast mineing have its superiorities, it will appears many important problems after changing over to the deep exploiting because of the change of exploiting the technological condition and influence of the natural factor of ore rock. With the stope going deeper downwards, the problems are more and more seriously. The problems include the extension of the automobile transportation distance, increase of its oil consumption and freight charges, the aggravation of environmental pollution that the tail gas caused. In the way, the question of automobile transportation of deep concave opencut causes people's attention more and more.In the basis of the analysis and compare of the advantages and disadvantages of the traditional means of combined transportations (belt conveyor, skip elevator), the transport conception of the completed opencut dump truck promotes system have been carried on deeper research and analysis. This article explained in detail the design conception and constitution of the automobile promotion transportation system and the analysis and prediction about technique, security and economy benefits according to the principle of the technique feasibility, security credibility and economy rationality.The automobile promotion system is not applied in home and carried on the theoretical research on a few mines at abroad at present. By this text listed promotion scheme and analysis and prediction on each scheme about technique, security and economy benefits, it shows us that the opencut automobile promotion system is a new-type equipment and technology with high production efficiency and development potentiality. From such respects astechnology, economy, security,etc, in exploiting the transportation system of the opencut, it is feasible and reasonable that the promotion system replace traditional automobile ramp transportation system, and realizable in the terms of designing , making and putting into practical application according to existing technology.According to the economy benefits and on the basis of meeting transportation demand, promotion system can greatly improve the automobile transporting efficiency, shorten the transportation time, decrease the cost of automobile management, maintenance, repair and transport consume.The design of opencut dump truck completed car promotes system has drawn lessons from the theory of inclined shaft, which use the powerful electromotor to scrolling the steel rope and pull the transport platform that carries the truck up to the needed plane. Then the truck is driven out of the platform. Equally, it can be used in the vacant automobile too. And on this basis, in order to try one's best to reduce the whole systematic fabrication cost, more fully utilize existing resources, the article introduces the promotion proposal of refitting the large-scale mining automobile, separating the tipping bin and the motive system. In theory, utilize of the automobile promotion system may work out following problems:· the transport distance is too long and waste a lot of time;· avoid the effect of environment factor, such as rain, snow, fog, etc.;· reduce a large amount of exhaust gas discharged in the climbing course, reduce the environment pollution;· meet demand for traffic volume;The completed opencut dump truck promotion system mentioned in this article is feasible in technique and has great value of application. It will be of great benefit to improve the economy benefit and prolong the exploitation.
