A kind of open-pit mining area diversion development transportation system

Abstract

The invention discloses a steering development haulage system used in an open-pit mining area. The system comprises a mining process in a single mining area and a steering mining process in mining areas. The steering development haulage system is derived based on an existing open-pit mine haulage theory and an ageing slope theory, the wild goose queue type development haulage system is arranged, secondary stripping during mining steering can be reduced, an end-slope haulage system is simplified, the inner dumping space is increased, and the haulage cost is reduced. The system is high in applicability, low in cost, good in economic effect and higher in popularization value. The system is not only suitable for an open-pit coal mine, but also suitable for other open pits.

Description

technical field [0001] The invention relates to an open-pit mine development transportation system, in particular to an open-pit mining area diversion development transportation system. Background technique [0002] As an important branch of the mining industry, surface mining undertakes more and more important coal mining tasks. Open-pit mining is generally adopted for deposits with thick overburden and thick coal seams. Due to factors such as production scale, mining intensity, equipment specifications and economic benefits, zoned mining is often used. Open-pit mines mined in subareas cannot avoid turning the mining area to continue. my country currently has more than 40 10-million-ton open-pit coal mines under construction and put into production, and 5 30-million-ton open-pit coal mines in production, all of which adopt partition mining and need to be diverted 2 to 4 times. During the diversion period, almost all of them face insufficient internal drainage space , Trans...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a pioneering transportation system that increases the inner row space, recovers the side coal, reduces the lifting height, shortens the distance of the car, and improves the overall benefit, so as to solve the problem of the existing partition mining. Insufficient inner row space, increased transportation distance, low equipment efficiency, transportation system transformation and unbalanced mining and stripping engineering caused by the turning period
