Abstract
The invention discloses a thin coal seam intelligent coal mining technology. A dual-roller coal mining machine is adopted to carry out comprehensive mechanical coal mining. The dual-roller coal mining machine comprises a first roller in the wind intake side and a second roller in the wind return side. When the cutting is carried out towards to the wind intake side, the first roller cuts the top coal, and the second roller cuts the bottom coal. When the cutting is carried out towards to the wind return side, the first roller cuts the top coal, and the second roller cuts the bottom coal. By the provided technology, the coal mining machine operator can always controls the coal mining machine in the wind intake side, thus the dust intake amount is largely reduced, the operator does not need to work under a damp environment, the work environment is greatly improved, and the harms to the health of the operator are reduced. Moreover, the existed video monitoring system can be better utilized, and the video quality and monitoring effect are both improved.
Description
Technical field
The present invention relates to a kind of fully-mechanized mining working coal winning technology method, particularly relate to a kind of comprehensive mining machinery coal-mining method using double-ended shearer.
Background technology
The flitting that fully-mechanized mining working uses, its cutting units is made up of two, left and right cylinder mostly.Tradition coal winning technology, see accompanying drawing 1-2, the direction run by coal machine, the cylinder being positioned at traffic direction front portion cuts top coal, and the cylinder being positioned at traffic direction rear portion cuts ground coal.This coal mining activity mode advantage is that in coal seam, most of coal is by cylinder cut on front portion, then falls on transporter, and small part coal is by back roll cut also clear coal, and this technique coal-winning machine effect of loading coal is good, and reduces coarse coal landing.
Coal mine fully-mechanized mining working, due to special working environment, needs to add forced ventilation and atomizing de-dusting.But coal-face section is limited, and air quantity is larger, and wind speed is higher, thus the coal dust caused flies upward more, and corresponding spray amount is larger.Air quality, the air visibility of the coal-winning machine return side (lower air port) caused thus are usually very poor.
Two cylinders of flitting, when normally producing, top is cut in a division of labor, and portion is cut off in a division of labor.Its dangerous matter sources is mainly on top, and upper cylinder will prevent from cutting back timber, cutting top board, and bottom roll is be embedded in coal to operate substantially, has again transporter to block.Workman is when operating coal-winning machine, and coal-winning machine driver mainly observes cylinder, and bottom roll is not seen substantially.According to current coal winning technology, when coal-winning machine runs toward uptake (namely inlet side), as shown in Figure 1, the observation condition of upper cylinder is better; But when coal-winning machine down run by air port, as shown in Figure 2, on coal-winning machine driver observation, cylinder will stand in the operation of lower air port, coal-winning machine produces a large amount of dust when running, one is that workman observes cylinder inconvenience in the environment that visibility is extremely low, far away not see, near and have the danger of being wounded by coal cinder; Two is breathe dust for a long time, and works in malaria, unhealthful, therefore has large quantities of coal miner to suffer from the occupational disease such as anthraco-silicosis, arthritis.Meanwhile, along with the development of coal mining automaticity, the monitoring of work plane Video Remote has become indispensable equipment.And current coal-mining method, when coal-winning machine down run by air port, video observes the cylinder of downwind side, due to poor visibility, is difficult to realize the long-range video monitoring to coal-winning machine.
Summary of the invention
For solving the problem, the present invention proposes a kind of comprehensive mining machinery coal winning technology using double-ended shearer, described double-ended shearer comprises the first cylinder of inlet side and the second tin roller of return side, when cutting to inlet side, described first cylinder cutting top coal, described second tin roller cutting ground coal; When cutting to return side, described first cylinder cutting top coal, described second tin roller cutting ground coal.
Preferably in coal mining process, described first cylinder is all the time as upper cylinder, and described second tin roller is all the time as bottom roll.
Preferred work plane is provided with video monitoring system, and described video monitoring system is for monitoring upper cylinder.
Method of the present invention is used to carry out work plane coal mining activity, coal-winning machine operating personnel can control coal-winning machine in inlet side for a long time, greatly reduce the soakage of dust, avoid working under humid conditions, the strong working environment improving workman, decreases the harm healthy to worker; Existing video monitoring system be can better utilize, video quality and monitoring effect improved.
Accompanying drawing explanation
Accompanying drawing 1 is the operating diagram to inlet side cutting in prior art coal winning technology;
Accompanying drawing 2 is the operating diagram to return side cutting in prior art coal winning technology;
Accompanying drawing 3 is the operating diagram to inlet side cutting in coal winning technology of the present invention;
Accompanying drawing 4 is the operating diagram to return side cutting in coal winning technology of the present invention.
Detailed description of the invention
Mode below by embodiment is described in further detail coal winning technology of the present invention.
Double-ended shearer comprises the first cylinder of inlet side and the second tin roller of return side, when cutting to inlet side, see accompanying drawing 3, its coal cutting mode is substantially identical with coal cutting mode of the prior art, uses the first cylinder cutting top coal of inlet side, use the second tin roller cutting ground coal of return side, now the first cylinder is upper cylinder, and it is in inlet side, and ventilation situation is better, surrounding environment is clear, dust is few, is convenient to the observation of staff and video system; When cutting to return side, see accompanying drawing 4, uncomfortablely to change, the position of bottom roll, only adjust the amount of feeding of coal-winning machine entirety, continue use first cylinder as upper cylinder cutting top coal, second tin roller cuts ground coal as bottom roll, now goes up cylinder and still can be in the good inlet side of ventilation situation, be convenient to the observation of staff and video system.That is, in coal mining process, the first cylinder is all the time as upper cylinder, and second tin roller, all the time as bottom roll, makes the first cylinder of inlet side all the time as the upper cylinder needing to observe in detail, the observability of cylinder in guarantee.
Use said method, because the environment of upper cylinder is more clear, video monitoring system monitoring upper cylinder, namely first cylinder that work plane can also be utilized to arrange, realize the automatic monitoring of working surface coal mining machine.Video monitoring system comprises video camera, camera and/or other visible ray monitoring equipment, and on the inlet side being arranged on work plane or coal-winning machine, lens direction is towards upper cylinder direction.Video monitoring system can be connected with work plane control centre and/or bracket controller, automatically starts, also can be opened by manual remote control when mining and starting.
The above; be only patent of the present invention preferably detailed description of the invention; but the protection domain of patent of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope of patent diselosesll of the present invention; the change that can expect easily or replacement, within the protection domain that all should be encompassed in patent of the present invention.
