Abstract

The invention discloses a method for mining coal through comprehensive mechanized solid filling, belongs to the field of coal mining techniques and relates to a coal mining method. The method comprises the following steps that: solids are conveyed to a charging well through a ground transportation system, wherein the charging well is provided with a tapered buffer, and the solids are gangues, pulverized coal ash, loess and lime; the solids fall down and are piled up after the pressure is reduced through the tapered buffer, and the piled-up solids are transported to a mined coal area for filling. The method for mining coal through comprehensive mechanized solid filling has the advantages that the area of a ground open ore slag yard can be greatly reduced or eliminated, the quality of the ecological environment of the mining area is improved, the movement of rock stratums can be effectively controlled, the safety in use of ground buildings can be ensured and the coal pressed below the buildings can be efficiently and mechanically recovered to the utmost extent.

Description

The method of comprehensive mechanization solids filling coal mining

Technical field

The invention belongs to the coal-mining technique field, relate to coal-mining method, be specifically related to a kind of method of comprehensive mechanization solids filling coal mining.

Background technology

Coal is as the main support energy of China; Along with the fast development of Chinese national economy, the industry such as electric power, iron and steel, railway that is positioned at the coal downstream strengthens the demand of coal year by year, and causing in recent years, coal mining speeds up; Along with the prolongation of the pit mining time limit with adopt dark extension; A collection of resource exhaustion mine progressively gets into residual adopting the stage, and the part mine gets into the decline phase, have in addition closing well change the line of production." aging " phenomenon in colliery has become the common problem of resource-type enterprise; Mine for the decline tendency is arranged has also caused enough attention, has in the face of the problem of " three times " (under building, under the railway, under the water body) pressure coal that can't exploit with conventional art in most of mining areas.

In decades; Press the coal problem in order to solve " three times ", a large amount of work has all been done by local governments at all levels and coal mining enterprise, and scientific and technical personnel have also carried out multinomial technological development and popularized work; The integral level of railways and water-bodies technology is enhanced; Studied and comprise multiple " three times " production techniques such as moving village's exploitation, band exploitation, limited thickness extrac tion, harmonic extraction, grouting in sepa rated bed exploitation, paste body filling exploitation, yet these technical costs are too high, and can not reach efficient mechanical mining; It is to realize by resettlement that the building that exploitation is at present come out presses down coal about 3/4; But the resettlement exploitation has caused the mass breaking subsidence area, causes serious ecology and environmental disruption, and exploitation also is not suitable for resettlement under the intensive building of many mining areas.

Simultaneously, opencut discharges a large amount of slags aborning, and traditional mode is directly to be stacked at the face of land, forms opencut deslagging field, the distinctive face of land, colliery.Along with pit mining, the transportation range of deslagging field deslagging and transit link be also in continuous increase, when wasting a large amount of manpower and materials, also caused problems such as environment pollution.

Therefore, researching and developing a kind of production technique that architectural complex press down problems such as the exploitation of coal scale property, solution solid waste discharge that solves, is the great scientific and engineering technical barrier that the mining area needs to be resolved hurrily.

Summary of the invention

The method that the purpose of this invention is to provide a kind of comprehensive mechanization solids filling coal mining.

The present invention realizes through following technical scheme:

A kind of method of comprehensive mechanization solids filling coal mining may further comprise the steps:

Solids is sent into the well that feeds intake that the taper snubber is installed through ground transportation system; Wherein said solids is spoil, flyash, loess, lime; Solids falls after the decompression of taper snubber and piles up, and then the solids of piling up is transported to the zone of mining and carries out filling.

Comprehensive mechanization solid material filling coal mining method of the present invention; Can significantly reduce or eliminate opencut deslagging field, ground area; Change the mining area ecological environment quality; And can effectively control the rock stratum and move and guarantee the above ground structure safe handling, recovery building maximum, efficiently mechanization presses down coal, and this Study on Technology has following significance:

(1) improves the mine coal mining rate; Prolong mine service-life: the solid waste filling is combined the technology of adopting and can be realized that building presses down coal work plane recovery ratio more than 85% under the building of research and development; Prolonged the length of service of mine; Simultaneously, extenuate personnel's problem of employment that resource exhaustion type mine brings, guaranteed the stable of mining area society;

(2) realize that solid waste such as slag is in down-hole treatment; Improve mining area periphery ecology and living environment: the successful implementation of this technology; Can solve the environmental destruction problem that ground release such as slag brings, improve the environment of mining area periphery, and human existence and living environment.

The specific embodiment

Embodiment 1

A kind of method of comprehensive mechanization solids filling coal mining may further comprise the steps:

Solids spoil and flyash are sent into the well that feeds intake that the taper snubber is installed through ground transportation system, and spoil and flyash fall through taper snubber decompression back and pile up, and then the spoil of accumulation and flyash are transported to the zone of mining and carry out filling.

Embodiment 2

A kind of method of comprehensive mechanization solids filling coal mining may further comprise the steps:

Send solids spoil, flyash with through ground transportation system into the well that feeds intake that the taper snubber is installed, solids falls through taper snubber decompression back and piles up, and then the solids of accumulation is transported to the zone of mining and carries out filling.

Embodiment 3

Solids spoil, lime and loess are sent into the well that feeds intake that the taper snubber is installed through ground transportation system, and solids falls after the decompression of taper snubber and piles up, and then the solids of piling up is transported to the zone of mining and carries out filling.

Claims (1)

1. the method for a comprehensive mechanization solids filling coal mining is characterized in that may further comprise the steps:
Solids is sent into the well that feeds intake that the taper snubber is installed through ground transportation system; Wherein said solids is spoil, flyash, loess, lime; Solids falls after the decompression of taper snubber and piles up, and then the solids of piling up is transported to the zone of mining and carries out filling.
