Description

Multifunctional downhole undercover machine

The invention relates to a multifunctional downhole undercover machine.

Background technique

When the coal mining face encounters the softness of the coal seam floor, the artificial undercover is required to maintain the height of the roadway as the working face advances. Even under normal work, the transfer machine and the belt conveyor often need to manually clean the floating coal to maintain normal production. The labor intensity of the employees is large. In the production process, a large number of materials and accessories are currently loaded and unloaded by manual chain hoists. The lifting of the chain hoists needs to be shed or lifted, which not only has a large workload, but also has low efficiency and waste. The material, more importantly, is safely hidden under the root-lifting point. When installing the equipment in the fully mechanized caving face, the installation and unloading of the front and rear chutes are also carried out by the manual chain hoist. The working face is cut into 200-300 lifting bolts, and the roof conditions are poor. At the same time, it is necessary to step down the shed to strengthen maintenance.
