Problems solved by technology

In the process of building the bridge, it is necessary to periodically build and dismantle the transport bridge. Since the existing Maibu tower bridge is built of rock and soil, this will cause a large amount of secondary stripping, increase the mining cost, and at the same time Increase the complexity of pit bottom operations and cause multiple disturbances to the slope, affecting the safety of open-pit mining

Abstract

The invention discloses an open pit mine stepping tower bridge device which comprises a road bridge, a hydraulic support and a scraper transporter. The road bridge is in a strip shape, the hydraulic support is supported on the bottom surface of the road bridge, and the scraper transporter is installed on the top surface of the road bridge. According to the open pit mine stepping tower bridge device, a stepping tower bridge is built through the road bridge and the hydraulic support instead of original stone soil, the secondary stripping amount of a mine is reduced. Besides, the road bridge, thehydraulic support and the scraper transporter can be reused after being dismantled, and the cost is reduced. According to the open pit mine stepping tower bridge device, coal is also transported through the scraper transporter, the force borne by the hydraulic support is continuously distributed, and the unit load is small.

Description

technical field [0001] The invention relates to the technical field of open-pit mining, in particular to a step-tower bridge equipment for open-pit mines. Background technique [0002] In open-pit mining mines with near-horizontal occurrence, in order to increase the side slope angle, reduce the stripping ratio, and improve the pit bottom transportation system, the method of stepping and building bridges is adopted to realize the continuous advancement of the open pit. In the process of building the bridge, it is necessary to periodically build and dismantle the transport bridge. Since the existing Maibu tower bridge is built of rock and soil, this will cause a large amount of secondary stripping, increase the mining cost, and at the same time It increases the complexity of pit bottom operations and causes multiple disturbances to the slope, affecting the safety of open-pit mining. [0003] Therefore, how to change the traditional stepping bridge and reduce the amount of se...
