Problems solved by technology

Obviously, most of the time is spent in the process of "shunting" in this method of ballasting, resulting in the process of ballasting accounting for 75-79% of the entire ballasting operation, and the work efficiency is too low
It also needs to be explained that, for this kind of operation method, in order to improve the operation efficiency, the tail of the loader is now lengthened, so that two empty wagons can be placed under the tail at a time, and one can be filled first, and then pushed a little. Fill up another mine car, so that when two mine cars are full, store the two heavy cars in the storage fork lane on the left according to the above shunting method, which improves the efficiency slightly, but it does not fundamentally Overcome the drawbacks of low efficiency inherent in this traditional method of ballasting
The present invention is mainly aimed at the currently widely used domestically-used ballasting operation method whose efficiency needs to be improved.

Embodiment 1

[0019] Embodiment 1, in conjunction with referring to figure 2 , a method for fast mucking out of three-dimensional operations in mine excavation, its related equipment and structures mainly include: a monorail crane 3 suspended on the roadway vault 1 anchor rod 2, an electric locomotive 4, an empty wagon (empty wagon) 5, a heavy Car 6, ground track 7, pick-up machine 8, etc. The monorail crane 3 is composed of a monorail 301 connected by sections of I-beams and a set of hoisting mechanism 302. Some existing mining machinery factories (such as Shijiazhuang Coal Machinery Factory) produce a series of cranes for other high-altitude operations. The "monorail crane" products in the field can be directly selected as the monorail crane 3 of this embodiment. The monorail crane 3 is hoisted on the anchor rod 2 of the vault 1, and the operating state of its hoisting mechanism can be operated by wireless remote control. Way.

Embodiment 2

[0022] Embodiment 2, see in conjunction with image 3 , a method for quickly removing muck in three-dimensional operations in mine excavation, its related equipment and structures mainly include: monorail crane 3 suspended on the roadway vault 1 bolt 2, electric locomotive 4, empty car 5, heavy car 6, ground Track 7, pick-up machine 8, etc. The monorail crane 3 is composed of a monorail 301 connected by sections of I-beams and a set of hanging mechanism 302. Some existing mining machinery factories (such as Shijiazhuang Coal Machinery Factory) produce a series of cranes for other transportation. For the "monorail crane" products in the field of work, this type of molded product can be directly selected as the monorail crane 3 of this embodiment. The monorail crane 3 is hung on the anchor rod 2 of the vault 1, and the operating state of its hanging mechanism can be controlled by wireless remote control. mode of operation.

Abstract

The present invention discloses a stereowork quick slag-discharging method in mine excavation. It mainly adopts the following two modes: one is an operation mode for conveying carriage along the tunnel ground track by means of motor car and another is an operation mode for overhead traveling empty carriage by means of overhead traveling device of carriage in the air under the bow of tunnel.

Description

technical field [0001] The invention relates to a method for removing muck in mine excavation, in particular to a method for quickly removing muck in three-dimensional operation. Background technique [0002] In our country, the tunneling construction generally adopts the "drill and blast method". The main work of this method includes four major links, namely drilling, blasting, ballasting, anchor spraying and so on. The "ballasting" related to the invention is to transport the blasted rock (commonly known as "ballast"), commonly known as "ballasting"; Rows of bolts, each bolt is several meters long, and coal mines generally require that the pull-out resistance of each bolt is not less than 5 tons, especially the bolts in the arch are the densest. Among the above-mentioned links, the ballasting work is the most arduous and time-consuming process. According to statistics, it generally accounts for about 50% of the working hours of the excavation cycle (ie drilling-explosion...
