Abstract

The invention relates to a safety protection method for the bottom shaft of an inclined shaft dumping yard, belonging to the technical field of mine safety protection. The invention comprises three steps: a safety sealing wall is arranged at the bottom shaft, and a composite support structure of which organically combines flexible support and rigid support Together; a sports car protection device is set up in the closed area in the middle, which can play a buffering role in the event of a transportation accident; a protective net and a water intercepting ditch are set at the fork of the dumping yard to ensure the safety of personnel and running water; the overall protection method solves the useless bottom of the inclined shaft dumping yard. In the event of a transportation accident after the wellbore is sealed, the transportation vehicles and transportation objects directly hit the wall without buffering, resulting in the expansion of the accident and the problem of insufficient safety protection capability.

Description

technical field [0001] The invention belongs to the technical field of mine safety protection, and in particular relates to a safety protection method for the bottom shaft of an inclined shaft dumping yard. Background technique [0002] In the process of mine development, the inclined shaft development method is widely used in mines due to its advantages of simple shaft construction, low initial investment, and large lifting capacity. The auxiliary inclined well is mainly responsible for the transportation of materials, equipment and gangue. For the multi-level development of the mine, the auxiliary inclined shaft should be equipped with a depot at each level to meet the orderly transportation of materials, equipment and gangue between the auxiliary inclined shaft and each level. , and other levels set the dumping field. As mine production progresses, some horizontal resources will be exhausted and mining will be developed to new levels. When the lower horizontal resource...
