Embodiment Construction

[0013] Such as figure 1 Shown, installation method of the present invention is as follows:

[0014] The first step: widen the width of the cut hole, which is one set of track width more than the width of the ordinary cut hole, generally 1.2 meters more. To strengthen the roof support, according to the conditions of the roof, use anchor belt nets with anchor cables or anchor belt nets with single pillars to support the widened roof.

[0015] Step 2: Lay double rails in the opening, lay the main rail 4 on the side close to the coal wall 3, and lay the auxiliary rail 5 at the installation position of the bracket; the main rail 4 and the auxiliary rail 5 are connected by the switch 2, and the installation distance between the switch 2 is not large. If it is greater than 100 meters, avoid repeated lifting distances that are too long, resulting in a slowdown in installation speed.

[0016] The third step: transport the coal shearer 8 from the lower slot to the lower part of the cu...

Abstract

The invention discloses a reverse-procedure installation technology for fully mechanized mining face. The technology comprises steps of: first enlarging the width of an open-off cut to satisfy the requirements of support installation and laying double tracks in the open-off cut; laying double tracks in the open-off cut: laying a main track at the side close to coal wall, and laying an auxiliary track at the support installation site; connecting the main track and the auxiliary track through a track switch; conveying fully mechanized mining equipment to a position below the open-off cut along a down crossheading; lifting the equipment to the lowest track switch by using a winch on the main track; and conveying the equipment to the installation site for upward installation gradually after track changing. The technology uses the down crossheading of the mining face to convey equipment, and the equipment is lifted upward first and then conveyed downward for the installation through enlarging the width of the open-off cut and laying the double tracks, so the reverse-procedure conveyance and installation speed is improved, the installation quality is ensured, and the security and reliability of the installation are increased.

Description

technical field [0001] The invention relates to the installation technology of fully mechanized coal mining face equipment. Background technique [0002] The installation of hydraulic supports, face conveyors and shearers in coal mine fully mechanized mining face is an important production preparation work, which directly affects the production connection and normal production organization of the mine. Therefore, the installation quality and Installation speed is critical. [0003] At present, the usual sequence of the existing fully-mechanized mining face equipment installation process is: 1. Transport the fully-mechanized mining equipment to the upper slot; Installation is called uplink installation. Therefore, it is necessary to require that the upper trough has the conditions for rail transportation or trackless rubber-tyred vehicle transportation. However, with the popularization of the gob-side entry retaining process, when the upper trough of the gob-side entry ret...
