Description
Technical field
The present invention relates to a kind of seam mining method, especially a kind of steeply-inclined seam mining recovery method.
Background technology
At present, it is achieved seam mining comprehensive mechanization has become a kind of trend. The mining coal-mining method that China adopts in thickness and super high seam, through practice for many years, has become as one the most successfully recovery method, it addition, mining height workface also obtain successful Application in thick coal-layer mining. But for high-dipping thin and medium seam, owing to coal seam thickness is limited, mechanical mining support apparatus generally all obtains and along inclined direction arranges, and owing to seam inclination is big, the generation of the accidents such as very easily causing equipment to glide, to topple over that is in tilted layout, the high efficiency that comprehensive mechanization production has, high safety, low-intensity advantage can play out completely. For many coal mining enterprises, employing in the majority or a kind of coal drilling machine recovery method, especially for steeply inclined thin and ultra-thin coal seam.
Patent CN101705820B discloses a kind of coal drilling machine recovery method, winning apparatus is a kind of coal drilling machine, coal drilling machine includes main frame, electric-control system, hydraulic system, drilling tool and aid system, four-axle linked formula drilling tool it is provided with 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 drill bit. This recovery method by drilling in tunnel in coal seam, it is achieved seam mining. But due to single drill pipe limited length, during work, it is necessary to rely on and connect many drilling rods, after being drilled a hole, necessary sectional dismounting drilling rod again, drill bit and the weight of drilling rod own are very big, dismount all time and effort consumings, and labor intensity is big, and production efficiency is low.
How to realize fully-mechanized mining, be still in the exploratory stage.
Patent CN2397258Y discloses a kind of digging and transport unit. Digging and transport generating set main body is made up of digging and transport machine, hydraulic support and thrust gear. Owing to digging and transport unit can control digging and transport machine, hydraulic support downslide problem preferably, therefore, adopt digging and transport unit exploitation half-edge coal seam, production efficiency relatively other recovery methods significantly improve, labor strength substantially improves, therefore, start to obtain good popularization and application in nearest one or two years. But it practice, adopt the exploitation of this digging and transport unit to there is also problems.
Firstly, since digging and transport machine intermediate beam stress is impacted relatively big, therefore that the requirement of strength of material is higher, making complete equipment manufacturing cost higher, nonetheless, intermediate beam is still that the parts comparatively lost, make maintenance cost also significantly high, and then make coal production enterprise use cost higher.Secondly, this digging and transport unit have to use heavy-duty motor that digging and transport machine could be driven to operate, and must also be equipped with control panel, transformator, strong switch, change speed gear box and cable etc. simultaneously, therefore, further increase the use cost of coal mining enterprise especially. And owing to needs use heavy-duty motor to drive digging and transport machine, so be also easy to occur cable leakage to hurt sb.'s feelings, the serious accident such as initiation fire, particularly with highly gassy mine, there is bigger potential safety hazard especially. Again, during the work of this digging and transport unit, owing to digging and transport machine is as an overall operation, therefore for complicated condition, it is necessary to adjust the work surface of length every now and then, adaptability shows very poor.
In sum, how realizing half-edge coal seam fully-mechanized mining still in the exploratory stage, adopting the exploitation of digging and transport unit is compare successfully a kind of comprehensive mechanization production method at present, but still there is many weak points.
