Description

Combine and adopt the coal drilling machine group and combine and adopt coal drilling machine
Technical field
The utility model relates to a kind of seam mining support apparatus, especially a kind of steeply-inclined seam mining support apparatus.
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, become a kind of the most successful exploitation method, another sunset L, and large mining and high comprehensive mining has also obtained successful Application in thick coal-layer mining.But for the high-dipping thin and medium seam, how to realize fully-mechanized mining, still in the exploratory stage.
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 comprised 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 drill bit.This exploitation method, by drilling in Nei Xiang coal seam, tunnel, realizes seam mining.But because single run of steel is limited, during work, must rely on connect many drilling rods, after having bored a hole, again must sectional dismounting drilling rod, the own weight of drill bit and drilling rod is very large, and dismounting is time and effort consuming all, and labour intensity is large, and production efficiency is low.
How to realize fully-mechanized mining, still in the exploratory stage.
Patent CN2397258Y discloses a kind of digging and transport unit.The digging and transport generating set main body consists 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, starting 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, due to larger to the stressed impact of digging and transport machine middle girder, therefore higher to the requirement of strength of material, make the complete equipment manufacturing cost higher, nonetheless, middle girder is still very to hold flimsy parts, make maintenance cost also very high, and then make coal production enterprise use cost higher.Secondly, this digging and transport unit must be used heavy-duty motor could drive the running of digging and transport machine, also must be equipped with control panel, transformer, strong switch, gearbox and cable etc. simultaneously, therefore, has further increased especially the use cost of coal mining enterprise.And drive the digging and transport machine because needs are used heavy-duty motor, so the serious accidents such as cable leakage is hurted sb.'s feelings, initiation fire also easily occur, especially for highly gassy mine, there is especially larger potential safety hazard.Again, during this digging and transport unit work, because the digging and transport machine is as an overall operation, therefore for complicated condition, need to adjust every now and then the work plane of length, compliance shows very poorly.
In sum, how to realize that the half-edge coal seam fully-mechanized mining is still in the exploratory stage, adopting the exploitation of digging and transport unit is current more successful a kind of comprehensive mechanization production method, but still has many weak points.
