Problems solved by technology

[0003] 1. The tunnel excavation section is small: the excavation section is generally 15M 2 about
[0004] 2. Large installed power and high energy consumption: Most of the installed power of fully mechanized excavation working faces is above 250kw; the installed power of continuous mining machines is as high as 2000kw or above
[0005] 3. Difficulty in support: the support of gun excavation and comprehensive excavation is still manual support at present
[0006] 4. Low efficiency: due to the longer time required for mechanical cutting and coal cutting than blasting and blasting, the support of blasting and comprehensive excavation is manual support, and many people are employed, so the speed is slow and the efficiency is low
[0007] 5. Poor adaptability: it is difficult for a fully mechanized excavator model to adapt to various sections
[0008] 6. Roof problem: At present, various excavation methods are operated under the empty roof, and advance support cannot be realized
[0009] 7. The recovery rate of coal resources is low, and resources are wasted seriously; due to the small excavation section, resources are wasted
[0012] 10. The production capacity of the mine is low and the safety factor is small
As the excavation cannot be mechanized, the production capacity of the mine and the safety factor of the mine are low

specific Embodiment approach

[0040] As shown in Fig. 1 and Fig. 2, it is the mechanical integration device of coal loading, coal transportation and bolt support after blasting and falling coal. It includes hydraulic system and oil tank, etc. 1, hydraulic control console 2, crawler walking part 3, coal transportation part 4, support part 5, hydraulic bolter 6; coal transportation part consists of shovel plate 401 and airborne rake claw 402 is made up of two parts, and the coal is transported by the scraper conveyor 403 at the rear part of the shovel plate. A platform 8 is fixed and installed on the underframe beam 7 of the crawler walking part, and a coal transportation part is fixed between the underframe beam and the platform. The front is adjusted to be in contact with the ground by the oil cylinder 404 of the coal transportation part, and the scraper conveyor for coal transportation is in the middle and rear of the underframe beam. The support part is three hydraulic props distributed in a triangle on ...

Abstract

The invention provides a blast-winning, coal loading, coal conveying and anchor rod-timbering mechanical integrated operating method and device. And the device mainly comprises: hydraulic system, hydraulic control table, track walking part, coal loading and conveying part, timbering part, and hydraulic anchor rod machine, and the method uses integrated device, scraper conveyor and gate coal conveyor; and its drivage circulating speed is 1m to 1.5 m, blast-winning and after the fumes have settled, making the integrated device enter into the operating site, and after completing coal loading and conveying, making anchor rod timbering; after completing the anchor rod timbering operation, making the integrated device exit the operating site and over 20 meters distant from the operating site, and then making drilling and blasting operation. And it improves explosion level of blast winning and resources recovery, and reduces operators.

Description

technical field [0001] The invention belongs to the underground tunneling technology of coal mines, and is a comprehensive mechanized tunneling operation method and device applicable to various shapes and sections of large, medium and small coal mines. Background technique [0002] At present, tunneling technologies such as blasting, fully mechanized and continuous mining are generally used in roadway excavation of various coal mines in my country. These technologies have the following problems: [0003] 1. The tunnel excavation section is small: the excavation section is generally 15M 2 about. [0004] 2. Large installed power and high energy consumption: Most of the installed power of fully mechanized excavation working faces is above 250kw; the installed power of continuous mining machines is as high as 2000kw or above. [0005] 3. Difficulty in support: the support of gun excavation and comprehensive excavation is still manual support. [0006] 4. Low efficiency: Beca...
