Abstract
A roadway support equipment for gob side entry retaining, is applicable to high-yield and high-efficiency Modern Pit when exploiting without coal pillar mining upper curtate, stays the supporting of the tunnel for lower curtate return air of establishing and safeguard along goaf; Be particularly useful for " three is soft " coal seam, the roadway maintenance of gob side entry retaining under the conditions such as roof cracking coal seam and contiguous seams unitized production.Equipment comprises: upper back timber, scalable lever plate, main supporting upright post, support hydraulic cylinder, base, the ears or side handles of a utensil etc.This equipment adopts hydraulic support to support and can ensure to work under constant-pressure conditions, and top board adopts face contact to add the stability of equipment and the equipment that effectively avoids bores end problem; This device structure is simple, easily realizes the labour intensity that automation reduces workman, is convenient to stay the tunnel of establishing to recover as early as possible to come into operation; And solve the technical barrier that gob side entry retaining is difficult to supporting very well.
Description
Technical field
The utility model relates to a kind of roadway support equipment of gob side entry retaining, is that one is applicable to high-yield and high-efficiency Modern Pit when exploiting without coal pillar mining upper curtate, stays the supporting for the tunnel of lower curtate return air and maintenance of establishing along goaf; Be particularly useful for " three is soft " coal seam, the engineering field such as roadway maintenance of gob side entry retaining under the conditions such as roof cracking coal seam and contiguous seams unitized production.
Background technology
China is explored along empty without coal pillar mining technology, i.e. edge air gallery technology from the 1980s.So-called edge air gallery technology is exactly by strengthening supporting or roadside support, and the haulage way of a upper section is remained the tailgate as next section in working face extraction process.Edge air gallery technology is the normally used a kind of technology of modernization high yield and high efficiency mine, and the driving amount that not only can reduce tunnel in this way adopted by mine, can also improve the rate of recovery of coal resources, and then slows down excavation replacement anxiety.Gob side entry retaining is generally applicable to girdle and the medium-thickness seam of exploitation gentle dip and inclination.
Present edge air gallery technology generally adopts and arranges bracket mould, and grouting filling forms a stifled obturation wall.Although this technology can reach the object in isolation goaf, due to workman's workload very much not, labour cost is higher, simultaneously likely causes taking over not in time; Also has most of edge air gallery technology, at upper curtate haulage drift near position, goaf, along with stope is constantly pushed ahead, single or the double close standing props of immediate support or grillage, such support technology is that point cantact is difficult to safeguard for roof cracking coal seam and " three is soft " coal seam conditions.
Summary of the invention
The object of this invention is to provide a kind of roadway support equipment of gob side entry retaining, it is high that it effectively solves the labour cost that current gob side entry retaining causes, for roof cracking coal seam, and the construction difficult problem of " three is soft " coal seam and contiguous seams unitized production not easily supporting.This equipment can ensure to work under constant-pressure conditions, and the equipment that effectively avoids bores the end, easy to operate, and safety work easily realizes the labour intensity that automation reduces workman.The draft type adopting " two enter a time " at working face extraction simultaneously, the effective problem solving fully-mechanized mining working gas at upper corner and gather.
For achieving the above object, the utility model provides a kind of roadway support equipment of gob side entry retaining, comprise back timber, stretchable waste rock stopping plate, main supporting upright post, support hydraulic cylinder, base, it is characterized in that: described upper back timber and stretchable waste rock stopping plate hinged, stretchable waste rock stopping plate and base three bolts affixed; Main supporting upright post lower end and base hinged, the ears or side handles of a utensil of main supporting upright post upper end and stretchable waste rock stopping plate upper end are hinged, and the ears or side handles of a utensil at support hydraulic cylinder one end and waste rock board 2/3 place are hinged, and the ears or side handles of a utensil of the support hydraulic cylinder other end and upper back timber middle part are hinged to be formed.The width range of described stretchable waste rock stopping plate is 1500 ~ 2000mm, and telescopic extensions is 2500 ~ 4000mm.The width range of upper back timber is 1500 ~ 2000mm, and length range is 3000 ~ 5000mm.Described main supporting upright post is double acting two-pass hydraulic cylinder, and working resistance is 5000 ~ 7000KN, and support hydraulic cylinder is double acting multiple-pass hydraulic cylinder, and working resistance is 5000 ~ 10000KN.The width range of described base is 1500 ~ 2000mm, and length range is 400 ~ 700mm.
beneficial effect
The roadway support equipment of a kind of gob side entry retaining that the utility model relates to has the following advantages compared with existing equipment:
1, this equipment adopts hydraulic support stand can ensure to work under constant-pressure conditions, and top, base plate adopt face contact, increase the stability of equipment, and the equipment that effectively avoids bores the end, adds tunnel bearing pressure;
2, this device structure structure is simple, easy to operate, ensures that job safety easily realizes automation, thus the labour intensity reduced a staff, decrease labour cost;
3, this equipment effectively solves in roof cracking coal seam, tunnel not easily supporting under " three is soft " coal seam and contiguous seams unitized production condition, is out of shape large construction difficult problem.
Accompanying drawing explanation
Fig. 1 is that the roadway support equipment (safeguarding support) of a kind of gob side entry retaining of the utility model puts in order schematic diagram in tunnel;
Fig. 2 is roadway support equipment (the safeguarding support) schematic diagram of a kind of gob side entry retaining of the utility model.
Detailed description of the invention
For further setting forth the utility model for the technological means that reaches predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and better enforcement example, be described as follows according to the roadway support equipment detailed description of the invention and effect thereof of inventing a kind of gob side entry retaining proposed.
Refer to shown in Fig. 2, this realizes novel the provided support apparatus along empty gob side entry retaining, this equipment being transported to side, upper curtate haulage way goaf, is main support post slip casting with movable pump station, makes stretchable waste rock stopping plate touch back and has certain setting load; Then being the slip casting of support hydraulic cylinder with movable pump station, make back timber support to back, and make it have certain active supporting force.
Refer to shown in Fig. 2, the support apparatus along empty gob side entry retaining provided by the utility model, when this equipment Removal is reused, be the reverse slip casting of support hydraulic cylinder with movable pump station, back timber is transferred; Then being the reverse slip casting of main support post with movable pump station, equipment being dropped to and is separated with top board, and equipment is removed.
