Description

A kind of novel girdle colliery underground mining a complete set of equipment
Technical field
The invention belongs to the coal mining apparatus field, relate in particular to a kind of novel colliery underground mining a complete set of equipment that is adapted to the complex geological condition thin seam mining.
Background technology
At present domestic fully-mechanized mining equipment and technology mainly are to northern coal seam geological condition design; Be adapted to the seam mining that the coal seam is thick, the inclination angle is little and Coal Seam Thickness Change is little; And the general minimum exploitation of the thin seam mining equipment of domestic present research and development highly is not less than 12m; And the tool installed power is little, and reliability is not high, and the incompatibility Coal Seam Thickness Change is big, dirt band and the many coal seams of tomography.And the most of girdle of China balk of southwest particularly; The inclination angle is big and varied in thickness big, dirt band and tomography are many; Reliability and compliance to equipment are had relatively high expectations, and at present domestic research to the girdle mechanical mining equipment under the complex geological condition also is in space state.
Adopt comprehensive mechanization equipment to exploit the production efficiency that has significantly improved coal; But because the girdle varied in thickness is big, tomography is many; Use fully-mechanized mining equipment the situation of cutting the top or cutting the end to occur through regular meeting; The raw coal ature of coal is declined to a great extent, usually need carry out washing, cause the productivity effect of mine also to be lower than big gun and adopt benefit.In addition, investment is built greatly in fully-mechanized mining equipment ore deposit, and peopleware is had relatively high expectations, and is unfavorable for promoting at most of medium and small colliery of China and girdle.
And artificial blow out exploitation, but there are shortcomings such as poor working environment, poor stability, labor strength are big because its investment is little, adapt to characteristics such as coal seam geological condition is wide and in part thin seam mining and medium and small colliery are exploited, occupied certain ratio.
Summary of the invention
In order to address the above problem; A kind of novel girdle colliery underground mining a complete set of equipment is provided; It has taken into account fully-mechanized mining and artificial advantage of blowing out exploitation, has realized the mechanization supporting, coalings, transports operations such as coal, perforating, have the coal seam of adaptation scope wide, go into that worker's labour intensity is less, characteristics such as exploitation high efficiency, investment are little; Particularly realize the mechanization walking and the perforating of rig, significantly reduced working strength of workers.
A kind of novel girdle colliery underground mining a complete set of equipment comprises hydraulic support and drag conveyor, hydraulic support is used for the face roof supporting, the push-and-pull conveyer is coaling and protection equipment when avoiding blowing out to the impact of equipment, conveyer is used to transport coal and coalings; Also comprise the hydraulic drill rig car that can on conveyer, walk, many hydraulic drill rigs are housed on the hydraulic drill rig car, hydraulic drill rig carries out the mechanization perforating according to the borehole status requirement.Hydraulic support is provided with and protects the coal plate, protect the coal plate when the face firing coal breakage and the gripper shoe on drag conveyor overlap joint form confined space; Can rotate after the hydraulic drill rig car uses and put into drag conveyor and adopt the sky side.Each hydraulic drill rig car is responsible for the perforating in certain zone, as power resources it is walked through the high-pressure emulsion on the hydraulic support at work plane, and utilizes high-pressure emulsion to drive hydraulic drill rig and carry out perforating.After perforating finished, hydraulic drill rig can rotate put into conveyer old man side, and support stretches out and protects the coal plate and the conveyer support ear joins, thereby formed confined space, and the protection working face equipment avoids blowing out the injury of avalanche coal cinder.
The hydraulic drill rig car comprises mainframe, hydraulic drill rig, gyro black assembly, running part, hydraulic system, cooling system.Mainframe adopts the general frame structure, has only connection between each parts, does not have machine driving.Hydraulic drill rig connects with mainframe through rotating part, and rotating part comprises extension sleeve, is the telescopic structure, make rig can the realization level, vertical both direction rotates, the while can also go up and down; Running part adopts high-pressure emulsion to drive hydraulic motor as driving power, through gear-pin rail or gear-tooth bar walking; The rig perforating adopts high-pressure emulsion that power is provided, and the perforating action is operated through hydraulic control valve.
Hydraulic support is a standing shield hydraulic support, and hydraulic support is a standing shield hydraulic support, and it has the back timber structure, and the back timber structure comprises integral top beam and extensible canopy, is equipped with on the integral top beam and protects the coal plate.Protect the coal plate for one or more levels structure, both sides are provided with round, and rubber can be installed, and can overlap with drag conveyor after protecting the coal plate and stretching out, thereby can prevent to blow out that the avalanche coal cinder falls into goaf one side.
Drag conveyor is made up of head driving section, tail driving section, lead-over groove, intermediate channel, support ear, ramp plate, cable channel.Plate headstock in the dwarf forms level is adopted in head driving section, tail driving section structure, in the unloading mouthful in plate height and the intermediate channel plate height drop be controlled at reasonable range; The middle part baffle plate groove is helped increases the triangular support piece, can protect coal plate overlap joint with support and form confined space; Cable channel adopts detachable full-closed structure, and little, the compact conformation of size can also be protected cable and water pipe.
The present invention is owing to combined fully-mechanized mining and the artificial characteristics of exploiting of blowing out; Adopted and to have walked at face machinery; And the hydraulic drill rig that carries out the mechanization perforating carries out, and realized the mechanization supporting, coalings, operation such as perforating, has characteristics such as the coal seam of adaptation scope is wide, hand labor intensity is less, production efficiency is high, investment is little; Particularly realize the mechanization walking and the perforating of rig, significantly reduced working strength of workers.
