Description
Technical Field
The invention relates to the technical field of underground roadway tunneling and working face mining and transportation of a coal mine, in particular to a method for arranging fully mechanized caving face conveying and crushing equipment with front overlapped parts and back crossed parts.
Background
The intelligent mining technology of the working face of the medium and thick coal seams in China is developed rapidly, and comprehensive mechanical top coal caving mining is one of high-efficiency mining methods. The existing fully mechanized coal mining face conveying equipment generally adopts the following two arrangement methods: the first is front end unloading and rear end unloading, namely the fully mechanized caving face consists of a front end unloading conveyor, a rear end unloading conveyor and a reversed loader; the second is front end unloading and back cross side unloading, that is, the fully mechanized caving face is composed of a front end unloading conveyor, a back cross side unloading conveyor and a reversed loader. The head part of the end-discharge conveyor and the discharge chute of the transfer conveyor are arranged in an up-and-down lap joint mode, and fixed connection positions are not provided, so that the discharge point is unstable, the coal discharge effect is poor, and the coal discharge flow direction at the end of the conveyor is not consistent with the coal conveying direction of the transfer conveyor, so that the coal flow is not smooth in operation; the front parts of the two arrangement methods both adopt end-discharge conveyors, and due to the influence of the coal mining process and the uneven underground floor, the machine head of the front conveyor can move back and forth, so that the situation that the top coal discharged from the rear part smoothly passes through the front coal passing channel is prevented; due to the structural limitation of end-discharge type, the conveyor can only realize two-drive arrangement, and the conveying capacity is poor; if the large coal blocks jacked down from the rear part are not broken, the phenomenon of scraping and blocking can occur when the large coal blocks pass through the coal passage at the front part, and the unloading and the transportation of the coal are seriously influenced. Therefore, the design of the arrangement method for stabilizing the unloading point, smoothly running the coal flow and improving the conveying capacity is very important.
Disclosure of Invention
The invention aims to provide a method for arranging fully mechanized caving face conveying and crushing equipment with front parts overlapped and rear parts crossed, so that the stability of a unloading point is realized, the smooth coal flow transportation is ensured, and the conveying capacity of a fully mechanized caving face conveyor is improved.
The purpose of the invention is realized by the following technical scheme: in order to achieve the purpose, the fully mechanized caving face conveying equipment arrangement method designed by the invention is different from the conventional fully mechanized caving face conveying equipment arrangement method. The first one is that the front conveyor is lapped and laterally unloaded and the rear conveyor is crossed and laterally unloaded, and the front conveyor is laterally unloaded, wherein a machine head is located above a discharging groove of the reversed loader and is vertically lapped with the discharging groove of the reversed loader, an upper chain channel and a lower chain channel of the front conveyor are located above the upper chain channel and the lower chain channel of the reversed loader, and the machine head of the front conveyor provides a coal passing space for the reversed loader bearing the rear coal flow and realizes the unloading of the front coal flow. The unloading part of the machine head of the rear conveyor and the tail part of the reversed loader are connected into a whole, and the upper chain channel and the lower chain channel of the rear conveyor and the upper chain channel and the lower chain channel of the reversed loader are arranged in a staggered cross manner, so that the unloading of the top coal flow at the rear part is realized. The second is that the crusher is arranged between the front conveyor head and the rear conveyor head and is connected with the discharge chute of the reversed loader, and the large coal blocks jacked down from the rear part are crushed by the crusher to ensure that the rear coal flow smoothly passes through the front passage. And thirdly, the structures of the lapping side-dumping conveyor and the cross side-dumping conveyor can realize double-drive or triple-drive arrangement.
The invention has the following beneficial effects: a more reliable arrangement method is provided for fully mechanized caving face equipment arrangement, so that the unloading position is stable, smooth coal flow transportation is facilitated, and the conveying capacity of front and rear conveyors of the fully mechanized caving face is further improved.
