Abstract

The utility model discloses a comprehensive mechanized solid filling coal mining device and relates to a coal mining device. The comprehensive mechanized solid filling coal mining device comprises a ground transportation system; the tail end of the ground transportation system is arranged above a feeding pipeline; a storage hopper with a tapered lower part is connected below the feeding pipeline; a tapered buffer is arranged in the storage hopper; the bottom of the tapered buffer is provided with a signal sensor; and a feeding machine is mounted at the bottom of the storage hopper. The comprehensive mechanized solid filling coal mining device has the advantages that the ground transportation system can control the feed quantity of a material, the tapered buffer can effectively lower the impact of the filling material on the storage hopper, the signal sensor can detect whether the storage hopper is full or not, so that the ground solid filling material is safely and efficiently transported to mined-out areas, and the comprehensive mechanized solid filling coal mining device has a simple structure and is easy in popularization.

Description

Comprehensive mechanization solids filling coal mining device

Technical field

The utility model relates to the coal mining device, is specifically related to comprehensive mechanization solids filling coal mining device.

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, research and develop a kind of with solid waste as filler, the coal-mining method to filling is carried out in the goaf can realize that " three times " press the exploitation of coal scale property, solves the emission treatment problem of solid waste simultaneously.But, how solid waste is transported to the goaf safely and efficiently, fill, be the restraining factors that the restriction filling mining is promoted.

Summary of the invention

The purpose of the utility model provides a kind of comprehensive mechanization solids filling coal mining device.

The utility model is realized through following technical scheme:

Comprehensive mechanization solids filling coal mining device; Comprise ground transportation system; The end of ground transportation system is located at the pipeline top that feeds intake, and the pipeline below that feeds intake connects the storage bin that the bottom is taper, is provided with the taper snubber in the storage bin; The bottom of taper snubber is provided with signal transducer, and the storage bin bottom is equipped with feeder.

During work; Ground transportation system is sent solid material into the pipeline that feeds intake, and after the taper snubber decompression on storage bin top, falls into the storage bin bottom; When the solid material in the storage bin material reaches the signal transducer desired location; Signal transducer sends signal and is passed to ground transportation system, stops feeding, and the feeder of bottom is transported to the goaf with material.

The utility model ground transportation system can be controlled the injected volume of material; The taper snubber can effectively reduce the impact force of inserts to storage bin; Whether signal transducer can detect storage bin and buy securities with all one's capital; Thereby ground solid filling material is transported to the goaf safely and efficiently, simple in structure, be easy to promote.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Among the figure: 1-transports on ground system, 2-feed intake pipeline, 3-taper snubber, 4-storage bin, 5-signal transducer, 6-feeder.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Comprehensive mechanization solids filling coal mining device as shown in Figure 1; Comprise ground transportation system 1; The end of ground transportation system is located at pipeline 2 tops that feed intake, and pipeline 2 belows that feed intake connect the storage bin 4 that the bottom is taper, are provided with taper snubber 3 in the storage bin 4; The bottom of taper snubber 3 is provided with signal transducer 5, and storage bin 4 bottoms are equipped with feeder 6.
