Description

technical field

[0001] The invention relates to a support device, in particular to a device for supporting a mine roadway. Background technique

[0002] With the extraction of coal resources, the burial depth of mining coal seams must increase, and the expansion of mining scale and the improvement of mechanization level have accelerated the development of production mines to the deep. However, due to the continuous increase of mining depth, the geological environment continues to deteriorate, the ground stress increases, the number of broken rock masses increases, the amount of water leakage increases, and the ground temperature rises, resulting in a series of problems such as the deterioration of the operating environment, difficulties in roadway maintenance, and more geological disasters. Under the condition of deep well mining, the appearance and frequency of geological disaster accidents such as roadway deformation and rockburst in the mining process are obviously differ...
