Embodiment Construction

[0016] Referring to Fig. 1, a soft bladder 1 that can be filled or discharged is provided. The inflated shape of the soft bladder 1 is a wall stack, and the inflated wall stack-shaped soft air bag 1 stands upright on the fully mechanized mining face, with the lower end Bottom plate, and its top 2 and two side parts 3 coincide with the roof of the roadway and the side walls of the roadway respectively to form the sealing wall at the end of the fully mechanized mining face.

[0017] In specific implementation, in order to facilitate positioning and movement, the corresponding structural settings may also include:

[0018] On one side of the bladder 1, a liftable connecting rod 4 connected with the fully mechanized mining support in the roadway is set, and traction ropes are respectively arranged at different positions of the bladder 1, including the left traction rope 7 and the right side of the top traction rope 8. Side traction rope 9, each traction rope also can be arranged o...

Abstract

The movable capping safe air-pocket of the working-face end in the integrated mining is characterized in that: a soft cyst is set for inflating or bleeding air. The inflatable shape of the soft cyst is pier. It erects on the base plates of the upper and lower ends of the integrated mining working-face. Its roof and both side parts are anastomotic with the roof board and the two side boards of the tunnel separately to form the capping wall of the integrated mining working-face ends. The invention takes place of the existing capping mode with coalsacks hacking and building wall, which can lighten the workers' working strength, save the resources and cost and improve the capping effect and reliability.

Description

Technical field: [0001] The invention relates to an end plugging device for fully mechanized mining working faces used in the safe production process of coal mines, more specifically, an end plugging device especially suitable for fully mechanized mining working faces in high-gas coal seams and outburst coal seams . Background technique: [0002] With the continuous deepening of coal mining depth, there are more and more high-gas coal seam mining faces, and with the continuous improvement of coal mining technology, comprehensive mechanized coal mining faces are becoming more and more popular. While the comprehensive mechanized coal mining technology greatly improves the output, benefit, safety, and reduces the labor intensity of workers, there are still some aspects that need to be improved urgently. The end sealing technology of high-gas fully mechanized coal mining face is one of them. [0003] At present, most of the top and bottom ends of the fully mechanized mining fac...
