Abstract

The invention relates to the technical field of strip mine slope mining, in particular to a stepping type walking platform. The safe and efficient green mining of remanent coal in a strip mine slope is achieved, the demands of strip mine slope mining are met, and the recovery rate of slope remanent coal is effectively improved. The stepping type walking platform is located outside a mining cavern,and includes an upper platform, a lower chassis and a moving mechanism; and the upper platform and the lower chassis are integrally connected through the moving mechanism, the upper platform is provided with an electrical system, a hydraulic system and a cable rolling roller, and a working platform is arranged on the upper part of the lower chassis. The stepping type walking platform can realizethe safe and efficient green mining of slope remanent coal resources, significantly improve the technical strength of the strip mine slope mining in China, and bring significant economic and social benefits to enterprises.

Description

technical field [0001] The invention relates to the technical field of side mining in open-pit mines, in particular to a step-by-step walking platform. Background technique [0002] With the rapid development of the production and construction of open-pit coal mines in my country, the amount of side-pressed coal has reached 500 million tons. If a large number of open-pit side-pressed coal resources cannot be mined safely and efficiently, it will cause great waste of resources and environmental damage. The side mining technology of open-pit coal mines is to maximize the mining of side coal resources on the premise of minimizing the damage to the surface rock and soil cover and ground vegetation. This technology will basically not cause adverse effects on the environment and other resources, and can achieve a lot Good economic benefits. [0003] For open-pit coal mine side coal pressing and residual coal mining technology, developed countries in Europe and the United States d...
