Abstract
The invention particularly relates to a fully-mechanized coal mining face conveying process which solves the problem that by means of an existing fully-mechanized coal mining conveying process, resources 100 m away from a mining stop line cannot be mined. The fully-mechanized coal mining face conveying process includes the following steps that when a coal mining face is advanced to the position 100 m away from a mining line, a belt in a crossheading is detached and conveyed out, a 40T scraper conveyor is laid in the crossheading, a reversed loader and a crushing machine are laid in a coal output cross opening, mining is conducted continuously, a coal mining machine is connected to a scraper conveyor firstly after conducting coal falling, a head of the scraper conveyor is connected to the 40T scraper conveyor perpendicular to the scraper conveyor. A head of the 40T scraper conveyor is connected to the reversed loader arranged in the coal output cross opening. The reversed loader is provided with the crushing machine and finally connected to a belt machine to convey the coal out. The fully-mechanized coal mining face conveying process is reasonable in device arrangement, the coal mining face can be further advanced by 90 m, efficiency is improved greatly, and meanwhile the pressure brought by tense extracting joining is relieved.
Description
Technical field
The present invention relates to the delivery technology of underground coal mine, be specially a kind of fully-mechanized mining working transportation technology.
Background technology
At present, the comprehensive of down-hole use adopts transportation technology, coal-winning machine coal breakage---drag conveyor---elevating conveyor (crushing engine)---belt conveyor, due to the large frame of belt, switch cart, crushing engine and the nearly 100m of elevating conveyor length, fully-mechanized mining working stops adopting line-spacing two lane crossheading and is generally 100m, 100m resource beyond stop line cannot back production, the old ore deposit nervous for Linking up digging, resource is day by day exhausted, causes the huge wasting of resources and is connected pressure.
Summary of the invention
The present invention in order to solve existing combine adopt 100m resource beyond transportation technology stop line cannot the problem of back production, provide a kind of fully-mechanized mining working transportation technology.
The present invention adopts following technical scheme to realize: fully-mechanized mining working transportation technology, comprise the following steps, when the advance of the face very adopts line 100m to distance, belt in crossheading is removed and transports, being installed to be laid on to be layed in crossheading and by elevating conveyor and crushing engine by 40T drag conveyor produces coal in horizontal river, continue exploitation, first drag conveyor is accessed after coal-winning machine coal breakage, handpiece of scraper conveyer receives the vertically arranged 40T drag conveyor with drag conveyor, 40T handpiece of scraper conveyer receives the elevating conveyor being arranged in and producing coal in horizontal river, elevating conveyor is provided with crushing engine, elevating conveyor finally accesses conveyor and is transported by coal.
Beneficial effect of the present invention is as follows: be arranged in crossheading by 40T drag conveyor, and elevating conveyor and crushing engine are layed in produce coal in horizontal river, such reasonable Arrangement equipment, make work plane not by the restriction of the large frame of belt, switch cart, crushing engine and the nearly 100m of elevating conveyor length, 90m can be advanced more, greatly improve efficiency, for fully-mechanized mining working circulation 0.6m, 3 classes of systems, per tour 8 circulation, 18.7 classes can be done more by comprehensive team of adopting, and alleviate the pressure of Linking up digging anxiety simultaneously.
Accompanying drawing explanation
Fig. 1 is that existing mechanization mining face transporting device arranges schematic diagram;
Fig. 2 is that mechanization mining face transporting device of the present invention arranges schematic diagram.
Detailed description of the invention
Fully-mechanized mining working transportation technology, comprise the following steps, when the advance of the face very adopts line 100m to distance, belt in crossheading is removed and transports, being installed to be laid on to be layed in crossheading and by elevating conveyor and crushing engine by 40T drag conveyor produces coal in horizontal river, continue exploitation, first drag conveyor is accessed after coal-winning machine coal breakage, handpiece of scraper conveyer receives the vertically arranged 40T drag conveyor with drag conveyor, 40T handpiece of scraper conveyer receives the elevating conveyor being arranged in and producing coal in horizontal river, elevating conveyor is provided with crushing engine, and elevating conveyor finally accesses conveyor and transported by coal.
In specific implementation process, drag conveyor is connected transloading mode, 40T drag conveyor and elevating conveyor connection transloading mode with 40T drag conveyor is that those skilled in the art easily realize.
