Abstract
Underground coal mine needs often to arrange driving face, and the supporting of driving face can not efficiently be carried out, its solution is applied one exactly and can be provided temporary lining but not affect drivage efficiency, do not affect again the underground coal mine Provisional support for tunnelling face of bolt support operation, it belongs to field of coal mine safety simultaneously.The utility model is by temporary lining ceiling (1), temporary lining ceiling is connected with temporary lining canopy base (3) by hydraulic column (2), temporary lining canopy base is connected by hydraulic telescopic arm (5) with bolt support protection canopy base (4), bolt support protection ceiling (6) is connected with bolt support protection canopy base (4) by hydraulic column (2), wheel (7) is had under base, bolt support protection ceiling has circular port (8), and there is baffle plate (9) temporary lining canopy front end.This supporting shed structure is simple, novel, unique, simple, convenient, is that of temporary support for drivage face field innovates greatly, remarkable in economical benefits.
Description
Technical field
The utility model relates to a kind of temporary lining in driving face in coal mine tunnel, belongs to field of coal mine safety.
Background technology
As everyone knows, along with the increase to coal demand, mining depth is growing on and on, and geological environment is badly changed.Along with the increase of geostatic stress, ground temperature constantly raises, and engineering takes place frequently in carrying out accident, and serious accident increases, and wants smooth recovery of subterranean resources, avoids danger and disaster, and it is primary concept that staff will have shaft production safely.Underground coal mine is in order to adapt to the demand of production and carrying out smoothly of work in every, and need often to arrange driving face, one of emphasis of driving face in coal mine Roof Control is being met head on.Normal construction technique after explosion or tunneling machine cutting complete is temporary lining and permanent support.The personnel that now meet head on than comparatively dense, especially frame canopy or the personnel that to install when the links such as anchor pole beaten by rig near empty top zone.Although the measure such as to tap, still have wall caving and fall the situation generations such as top, this is the weak link of Roof Control.For a long time owing to lacking effective temporary support facility, majority is the operation such as perforating, muck, supporting under sky top or approximate empty top, is difficult to realize safety in production.For guaranteeing the personal safety of excavation operation personnel, avoiding empty top operation, temporary support for drivage face problem must be solved.Be badly in need of one and can provide temporary lining, but do not affect drivage efficiency, do not affect again the novel temporary lining canopy of bolt support operation simultaneously.Thus improve tunnelling Safety Control of Roof level, effectively increase the safety factor of meeting head within the scope of empty top, for operating personnel creates safe operating environment, realize longer safety period.This safety and stability, the supporting intensity that can solve traditional simple protection in tunnelling are rapidly and efficiently low, area is little, efficiency is low, ageing and poor stability, driving and supporting be without the difficult problems of operation method parallel operations.For realizing driving face without sky top and efficient parallel operation, the safety and the driving speed that improve roadway construction provide important technical support.
Summary of the invention
The purpose of the present utility model is just to provide one can be used for temporary lining, but does not affect drivage efficiency, does not affect again the novel temporary lining canopy of bolt support operation simultaneously.
The present utility model comprises temporary lining ceiling, temporary lining ceiling is connected with temporary lining canopy base by hydraulic column, temporary lining canopy base is connected by hydraulic telescopic arm with bolt support protection canopy base, bolt support protection ceiling is connected with bolt support protection canopy base by hydraulic column, wheel is had under base, bolt support protection ceiling has circular port, and there is baffle plate temporary lining canopy front end.During work, underground coal mine Provisional support for tunnelling face follows driving face closely and meets head on, good protective action is played to the region of not carrying out bolt support, directly can carry out bolt support operation by the circular port of ceiling upper end simultaneously, after completing a digging footage, by personnel control, it is made automatically to move forward.Underground coal mine Provisional support for tunnelling face, is characterized in that there is baffle plate temporary lining canopy front end, when explosion, can prevent broken coal petrography from directly impacting hydraulic column, play a protective role to hydraulic column.
The present utility model is applied to the temporary lining in driving face tunnel.
Namely the present utility model comprises temporary lining ceiling owing to adopting said structure, temporary lining ceiling is connected with temporary lining canopy base by hydraulic column, temporary lining canopy base is connected by hydraulic telescopic arm with bolt support protection canopy base, bolt support protection ceiling is connected with bolt support protection canopy base by hydraulic column, wheel is had under base, bolt support protection ceiling has circular port, and there is baffle plate temporary lining canopy front end.The temporary lining in driving face tunnel can be provided on the one hand, not affect bolt support operation again on the other hand, the efficiency of driving can not be affected again simultaneously.
Accompanying drawing explanation
Fig. 1 is supporting and protection structure figure of the present utility model;
Structure chart when Fig. 2 is support anchor rod supporting of the present utility model;
Fig. 3 is the step schematic diagram of the present utility model when moving.
Detailed description of the invention
The present utility model is done below in conjunction with drawings and Examples with detailed description.
As shown in Figure 1, Figure 2, Figure 3 shows, the present utility model comprises temporary lining ceiling (1), temporary lining ceiling is connected with temporary lining canopy base (3) by hydraulic column (2), temporary lining canopy base is connected by hydraulic telescopic arm (5) with bolt support protection canopy base (4), bolt support protection ceiling (6) is connected with bolt support protection canopy base (4) by hydraulic column (2), wheel (7) is had under base, bolt support protection ceiling has circular port (8), and there is baffle plate (9) temporary lining canopy front end.
To be laid by supporting shed at driving face and put in place, front end baffle opened, be close to driving face roadway's sides, bolt support personnel beat anchor pole (10) by the circular port of bolt support protection canopy upper end to top, tunnel.After explosion, after rock to be broken or coal cinder have been cleared up, front end baffle is turned back, by Artificial Control, temporary lining canopy is declined, depart from top board (step I), then by telescopic arm, temporary lining canopy is pushed away forward, make its front end close to the heading end end (Step II), then risen, supporting roof, and front end baffle is opened (Step II I).Then bolt support protection canopy is declined (step IV), shunk by telescopic arm, it is drawn forward (step V), by bolt support protection canopy jack-up (step VI) after putting in place, bolt support personnel beat anchor pole by the circular port of bolt support protection canopy upper end to top, tunnel, and so circulation is gone down.The object of the invention is under the condition not affecting drivage efficiency, carry out temporary lining and play anchor pole operation.Novel structure of the present invention, uniqueness, use simple, convenient, is that of driving face support field innovates greatly, applies and have great Social benefit and economic benefit.
