Description

Laying device and method for polyester fiber warp-knitted net for coal mine layered mining
Technical Field
The invention relates to a laying device and a method, in particular to a laying device and a method for a polyester fiber warp-knitted net for coal mine layered mining.
Background
The artificial roof adopted by the existing thick coal seam layered mining is usually manufactured by adopting the traditional metal net, the common plastic net and the like.
Metal mesh: the traditional metal net is used as an artificial roof for the layered mining of the thick coal seam, the area of a single net is small, the weight is large, the networking workload is large, the construction efficiency is low, the metal net is inconvenient to transport manually, the preparation work time is long, the metal net is easy to rust, the strength attenuation is fast, the service life is short, the strength of the lap joint of the net sheet and the net sheet is low, the lap joint is easy to tear,
common plastic net: low product strength, poor shearing strength, poor fatigue resistance, low connection strength between sheets, large labor intensity of manual transportation and manual lapping and low efficiency,
although the current industry also has a high-strength polyester fiber net layered mining and laying process, the current industry does not have a special bracket and a special device, and a smooth pedestrian passageway is not arranged, so that people are very difficult to enter the rear part of the bracket. Only the original top coal caving bracket is used, the rear space is narrow, the rear space is easy to have the phenomena of coal and waste rock surge when the bracket is moved, the rear space is blocked, the coal and waste rock are required to be manually cleaned before the net is transported, the cleaning time is long, the labor intensity is high, the purpose of laying the bottom net cannot be realized,
because of using the hydraulic support of non-special laying bed net, the rear portion space is narrow and small, there is not unblocked passageway, can't realize large tracts of land and pull, transport the polyester fiber net, even can pull, transport the polyester fiber net reluctantly, the fiber net is because of pulling the trawl along the bottom plate, and the friction causes the net piece to seriously damage, greatly reduced net piece intensity.
Because the hydraulic support with the bottom net laid without special use is used, when the hydraulic support moves, the polyester fiber net moves forwards along with the support, because the net unfolding rope and the support net unfolding pulley are in a parallel penetrating connection mode, the net unfolding rope blocks the transportation of the polyester fiber standby net, the standby net can not be preset, the process has no space for placing the standby net, the production must be stopped during the transportation of the net, the net unfolding rope must be manually penetrated, the manual networking seriously influences the yield, and the high-efficiency coal mining can not be realized,
in the coal mining process of a coal mine, when the coal seam is very thick, the coal seam is divided into a plurality of layers, generally 2 layers or 3 layers, and the layers are mined respectively, the mining process is called as 'layered mining', and in the mining process of the thick coal seam, the mining rate of the layered mining is about 95%, so that the layered mining is more beneficial to reasonably recovering coal resources, and a bottom net is laid on a bottom plate in a working face during the mining to serve as a top plate of lower layered mining; after the bottom net is laid, caving gangue in an upper layer can be supported when a next layer is mined, roof management in lower layer mining is facilitated, the bottom net is laid to form a stable roof structure, lower layer construction is generally required to be carried out at intervals, and cementation of the roof is more facilitated.
The technical scheme of the invention is made based on the technical problems, technical features and technical effects in the technical background of the applicant.
