Description

Technical Field

[0001] The utility model belongs to the field of mining, and in particular relates to an operating platform for rock drilling and filling in an underground mining field. Background Art

[0002] Underground mining production mainly uses rock drilling rigs to drill, blast, and drop ore, and then uses scrapers to load ore and trucks in the pit to transport the ore to nearby service chutes to complete the mining process. After the rock drilling rig completes the horizontal rock drilling, the operator needs to load explosives and detonators into the borehole. Whether this link can be completed safely and reliably is crucial to the quality of blasting.

[0003] At present, a lifting trolley is usually used to cooperate with operators to perform loading operations. For example, the Chinese invention patent application with publication number CN116877181A discloses a safety platform for rock drilling in mines, which uses a vertical lifting method to transport operators to a high place. The defects of this method are: 1. The device is restricted by the bottom plate of the mining area and cannot approach the rock working surface, resulting in low loading efficiency and quality, affecting the blasting quality and restricting mining production efficiency. 2. The top protective device is a horizontal structure. Although it can play a certain protective role, heavy stones and other falling objects accumulated on the top will cause collapse, which is prone to safety accidents. Utility Model Content
