Problems solved by technology

[0005] (2) Installation of hydraulic support and other equipment is carried out after the eye-cutting construction of the working face is completed, resulting in a long installation time of the working face and affecting the progress of production
[0006] (3) Due to the long transportation route of the hydraulic support, the transportation speed of the monorail crane is relatively slow, and the sole use of the support truck needs to harden the bottom plate of the transportation route, which requires a large workload and a long construction period
When the winch is used to haul the bracket, the resistance is relatively large, which seriously damages the floor of the roadway and poses a great hidden danger to transportation safety.

Embodiment Construction

[0027] Such as figure 1 with figure 2 As shown, after the development of the upper and lower level roads in the mining area, a common cut hole 2 with a width of 4.5 meters and a height of 3.7 meters is developed in the pre-mining working face to form a ventilation circulation system; where:

[0028] (1) The transportation method of the hydraulic support is:

[0029] (1) Disassemble the hydraulic support 4 on the well, reassemble it at the bottom of the well, and transport it to the replacement point. After loading the hydraulic support 4 with the support truck, directly transport the hydraulic support 4 to the upper end 1 of the cutting hole, and transport the support with the support truck Three vehicles are used as a group to ensure safety during uphill and downhill transportation.

[0030] (2) When the support truck is transporting, the hinged dry bridge is laid on the upper level lane. The surface increases the friction surface to improve the climbing ability of the su...

Abstract

The invention discloses a fast installation method of ten-million-ton scale fully mechanized caving face equipment and belongs to sinking and driving engineering of mines. The method is innovatively characterized in that open-off cuts on a working surface are widen to improve the transportation mode and installation method of a hydraulic support and the supporting mode of the open-off cuts. By virtue of the improvements, the installation time of the ten-million-ton scale fully mechanized caving face equipment is realized, the construction period is shortened and the installation progress of the working surface is accelerated.

Description

technical field [0001] The invention relates to mine shaft and roadway engineering, and is mainly used in fully mechanized caving working face cutting hole brush expansion and equipment installation engineering. Background technique [0002] At present, when the equipment is installed in the 10-million-ton fully-mechanized mining and fully-mechanized caving face of the coal mine, the first step is to cut the eye in the construction face. Due to the huge equipment, the span of the eye is generally 8-10m. The beams are used to strengthen the support, and then the equipment installation work on the working face is carried out. When the equipment is installed, remove the single pillar and replace it with a fully mechanized mining support. [0003] This brings up the following three issues: [0004] (1) The span of the working face cutout is large after the construction is completed, and the workload is heavy when using single pillars to strengthen the support. More than 1,000 ...
