Description

Technical Field

[0001] The utility model relates to the technical field of coal exploration, in particular to a supplementary exploration device for shallow coal in a reserve mining area. Background Art

[0002] With the continued high-intensity mining of shallow coal resources in my country, shallow coal reserves are becoming increasingly scarce. To maintain normal production, coal mining depths have gradually increased, even reaching depths of a kilometer in some mines. Currently, coal mining companies often use drilling to inspect the filling effect of goaf areas.

[0003] A cart-type drilling equipment is used when drilling. The cart-type drilling equipment is easy to move, but the height of the drill hole is fixed and the drilling position is limited. At the same time, the cart-type drilling equipment needs to be erected when used. Since the upright support platform has a large area, it is more laborious to erect and lay it flat. For this reason, we propose a supplementary exploration equipment for shallow coal in the reserve mining area. Utility Model Content
