B, by camera acquisition signal, through transmission equipment, development machine work picture is transferred in OPS, show in real time the duty of the each system of development machine, meet control, protection, demonstration, illumination and semiotic function demand to development machine; After tele-control system debugging preparation completes, control development machine is to pressing the coal cutting of coal driving, and the width of driving lane cave is 4～5m, and coal seam is automatically shoveled and delivered on belt conveyer by development machine after cutting, and transports driving lane cave to loading machine by belt conveyer;
C, along with the continuous propelling of development machine, add long belt in belt conveyer outside, utilize loading machine to retrodict and deliver to driving lane cave; When development machine driving is when stopping adopting line, development machine stops coal cutting, by Long-distance Control loading machine, belt-conveying machine equipment is withdrawn to driving lane cave, repair apparatus;
D, stay the coal column of establishing 1～1.5m, continue the coal mining of next driving lane cave, until the pressure coal completing in exploiting field reclaims.
Described to pressing coal driving coal cutting process as follows:
In OPS, first the cutterhead of development machine is adjusted to the cave lower right corner, lane incision coal body, coal cutting from below to up from right to left,, in the time cutting roof, controlling development machine slightly draws back, cut top coal, make back smooth, loaded after remaining coal by development machine, again the cutterhead of development machine is adjusted to lane cave base plate and carries out next circulation coal cutting.
Beneficial effect: coal mining system of the present invention is selected Long-distance Control development machine system, comprises a development machine and remote control chamber. Controlling equipment is made up of development machine electric control box, development machine electric control box, operating desk three parts, has remote wired control operation function, realizes separate men from machines, and when coal mining, people operates in the operating room of safety. Exploit main flow process comprise prepare clear up and select the coal cutting of Chu Caidong lane, development machine driving, development machine coaling, extend belt, belt to outward transport coal, loading machine casting, dig and exit tunnel to precalculated position, withdraw equipment, maintenance, again prepare the back production in next cave lane. Be conducive to realize opencut end side and be detained coal resources safety high-efficiency mining, can realize the unmanned automated mining of Long-distance Control, solved the little non-support in stoping operation space, have the problems such as labour intensity is large, exploitation continuity is low, potential safety hazard is many. Improve the coal resources rate of extraction etc., its production technology is simple, safe, efficient, production cost is low, has in the art practicality widely simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, one embodiment of the present of invention are further described:
End of the present invention is helped coal seam Long-distance Control driving recovery method, and main coal mining system is selected Long-distance Control development machine system, and it comprises a development machine 2 and remote control chamber. Controlling equipment is made up of development machine electric control box, operating desk two parts, has remote wired control operation function, realizes separate men from machines, and when coal mining, people operates in the operating room of safety. Exploit main flow process comprise prepare clear up and select Chu Cai lane cave 6, development machine 2 tunnel coal cutting, development machine coaling, extend belt, belt conveyer 3 to outward transport coal, loading machine 4 casting, dig that line 7 exits lane cave 6, withdraws equipment to stopping adopting, maintenance, the back production of again preparing next lane cave. The method has the features such as the coal resources rate of extraction of raising, production technology are simple, safety, efficient, production cost is low, is conducive to realize opencut end side and is detained coal resources safety high-efficiency mining.
As Fig. 1, shown in 2, end side coal seam 1 is positioned to reveal adopts under end side 5, belongs to the residual resource of end side, arranges that driving lane cave 6 carries out back production in coal seam, adopts the back production of the unmanned automation driving of Long-distance Control in exploitation process, and concrete steps are as follows:
