Description

Combine and adopt coal drilling machine group exploitation method
Technical field
The present invention relates to a kind of seam mining method, especially a kind of steeply-inclined seam mining exploitation method.
Background technology
At present, realize that the seam mining comprehensive mechanization has become a kind of trend.The mining coal-mining method that China adopts in thick and super high seam through practice for many years, has become a kind of the most successful exploitation method, and in addition, big mining and high comprehensive mining has also obtained successful Application in thick coal-layer mining.But for steeply inclined thin and medium-thickness seam, because coal seam thickness is limited, the mechanical mining support apparatus generally all gets along inclined direction and arranges, and because seam inclination is big, be in tilted layout and very easily cause the generation of accidents such as equipment glides, topples over, comprehensive mechanization is produced the high efficiency, high safety, the low-intensity advantage that have and is brought into play to come out fully.For many coal mining enterprises, still a kind of coal drilling machine exploitation method of employing in the majority is particularly for steeply inclined thin and ultra-thin coal seam.
Patent CN101705820B discloses a kind of coal drilling machine exploitation method, mining equipment is a kind of coal drilling machine, coal drilling machine comprises main frame, electric-control system, hydraulic system, drilling tool and accessory system, be provided with four-axle linked formula drilling tool in the one or both sides of main frame, drilling tool is by drilling rod, airduct, be made up of front transfer gear-box and the drill bit of 4 output shafts, power passes to drill bit through drilling rod, front transfer gear-box, and airduct is connected to the drill bit end.This exploitation method realizes seam mining by drilling in the coal seam in the tunnel.But because single run of steel is limited, during work, must rely on to connect many drilling rods, has bored a hole after, necessary sectional dismounting drilling rod again, the own weight of drill bit and drilling rod is very big, dismounting is time and effort consuming all, labour intensity is big, production efficiency is low.
How to realize fully-mechanized mining, still be in the exploratory stage.
Patent CN2397258Y discloses a kind of digging and transport unit.The digging and transport generating set main body is made of digging and transport machine, hydraulic support and thrust gear.Because the digging and transport unit can be controlled digging and transport machine, hydraulic support downslide problem preferably, therefore, adopt digging and transport unit exploitation half-edge coal seam, production efficiency obviously improves than other exploitation methods, labor strength obviously improves, therefore, beginning to be applied preferably one or two years recently.But in fact, adopt this digging and transport unit exploitation also to have problems.
At first, because bigger to the stressed impact of digging and transport machine middle girder, therefore higher to the requirement of strength of material, make that the complete equipment manufacturing cost is higher, nonetheless, middle girder still is the parts that comparatively lose, make maintenance cost also very high, and then make that Coal Production enterprise use cost is higher.Secondly, this digging and transport unit must use heavy-duty motor could drive the running of digging and transport machine, also must be equipped with control panel, transformer, powerful switch, gearbox and cable etc. simultaneously, therefore, has further increased the use cost of coal mining enterprise especially.And owing to need to use heavy-duty motor to drive the digging and transport machine, so serious accidents such as cable leakage is hurted sb.'s feelings, initiation fire also take place easily, especially for highly gassy mine, have big potential safety hazard especially.Again, when this digging and transport unit is worked, because the digging and transport machine is as an overall operation, therefore for complicated condition, need adjust the work plane of length every now and then, compliance shows very poorly.
In sum, how to realize that the half-edge coal seam fully-mechanized mining still is in the exploratory stage, adopting the exploitation of digging and transport unit is relatively more successful at present a kind of comprehensive mechanization production method, but still has many weak points.
Summary of the invention
The invention provides a kind of half-edge coal seam comprehensive mechanical mining method, cost of winning work plane compliance lower, safe, that complicated condition, length are changed at any time is strong.
