Technical Field

[0001] The invention relates to the technical field of mining storage, in particular to a mining flexible net storage device. Background Art

[0002] In recent years, in my country's coal industry, high-strength polyester fiber flexible mesh has been used in many mining areas. Beixinyao Mine of Datong Coal Mine Group has laid flexible mesh on the working face, reducing the cost of laying mesh and shortening the support period. Wanli No. 1 Mine 31 Coal 207 working face applied flexible mesh technology, reducing the labor intensity of workers and improving the efficiency of laying mesh. These working faces have proved that flexible mesh has good application value in terms of safety and economic benefits. Compared with traditional metal mesh, flexible mesh has the characteristics of light weight, safe use, and easy folding and curling.

[0003] The applicant has discovered that when laying nets on the working surface, the flexible net used is in the form of a net roll, and the flexible net in the form of a net roll is convenient for workers to lay the net on the working surface. According to field investigations in mining areas, it was found that there is a lack of devices that can effectively store and lay net rolls in mining areas where flexible nets are used. Workers need to carry the net rolls manually, and multiple workers are required to lay nets at the same time. In addition, in my country's coal industry, large-scale mechanical equipment such as gantry hydraulic supports and self-moving hydraulic supports have become important design trends for temporary support of tunnels. If a device is designed that can cooperate with hydraulic supports, can move with hydraulic supports, can store net rolls, and can facilitate net laying operations, it will improve the efficiency of support and reduce the labor intensity of workers.
