Problems solved by technology

[0007] Since the width of the cut hole has been excavated at the site is about 6.0m, the traditional method of installing the cut hole equipment cannot be installed in one step, and the rapid installation of the cut hole equipment directly affects the production and efficiency of the working face
[0008] In view of the above practical problems of on-site mining, how to realize the simple, fast and efficient installation of filling coal mining cutting equipment, save manpower and material resources, and at the same time make the working face quickly put into production, generate benefits, and overcome the installation of equipment behind the cutting hole in the prior art Insufficient space and technical defects have always been a technical difficulty in comprehensive mechanized solid filling coal mining

Embodiment 1

[0049] see Figure 8 , an installation method of comprehensive mechanized filling coal mining hole cutting equipment, the main operation and installation steps are as follows:

[0050] Step S11, first, according to the actual width and height of the section of the cut hole in the mine, carry out the bolt and anchor cable support for the cut hole;

[0051] Step S12, after opening the cut hole and completing the cut hole support operation, lay the first track on the side A of the coal wall; after the large part car of the scraper conveyor 6 enters the assembly room 5, use the winch 3 to move the large part Lift the car to the installation site, and install the various components of the scraper conveyor 6 along the first track;

[0052] Step S13, after the scraper conveyor 6 is installed, a second track is laid on the side of the goaf B, and the working surface support 7 is transported to the assembly room 5 for assembly;

[0053] Step S14, after the assembly of the working surfa...

Abstract

The invention discloses an installation method of comprehensive mechanized filling, coal mining and open-off cutting equipment. The installation method comprises the main steps: carrying out open-off cutting and open-off cutting shoring, laying a rail on the coal wall side, and transporting and installing a scraper conveyer; then, laying a rail in a goaf region, and transporting and installing a support; then making two gaps in a headpiece, and transporting and installing a coal mining machine; then transporting and installing a reversed loader by using a winch in a return air tunnel; finally laying a rail in the goaf region side after advance of the face by 3m, and installing a rear top beam of the support, a tamping mechanism and a porous bottom-dump conveyer. The installation method disclosed by the invention aims at solving the technical problem that the installation space of rear equipment is not enough after filling and coal mining front equipment is mounted, and a brand new method is provided for rapid installation of the comprehensive mechanized filling, coal mining and open-off cutting equipment. The installation method is simple, simple and convenient to operate and wide in practicability.

Description

technical field [0001] The invention relates to the technical field of coal mine and metal mine mining application, in particular to an installation method of comprehensive mechanized filling coal mining hole cutting equipment. Background technique [0002] With the continuous development of my country's "three downs" coal mining technology, the comprehensive mechanized solid material filling coal mining technology using gangue, fly ash, loess, construction waste and other solid materials as filling materials is becoming more and more mature. "The large-scale mining of coal and metal mines, and the effective filling of gobs have achieved the effect of improving the recovery rate of coal and metal mine resources, and at the same time solved the problem of solid waste gangue, fly ash, and metal tailings on the ground. To solve the problem of stacking and processing, the comprehensive mechanized solid material filling coal mining technology has important practical significance an...
