Description
Technical field
The present invention relates to a kind of seam mining support apparatus, especially a kind of steeply-inclined seam mining support apparatus.
Background technology
At present, realize seam mining comprehensive mechanization and 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 one the most successfully exploitation method, in addition, mining height workface also obtain successful Application in thick coal-layer mining.But for high-dipping thin and medium seam, how to realize fully-mechanized mining, be 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, four-axle linked formula drilling tool is provided with in the one or both sides of main frame, drilling tool is by drilling rod, airduct, be made up of the front transfer gear-box of 4 output shafts and drill bit, 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 coal seam in tunnel, realizes seam mining.But due to single drill pipe limited length, during work, must rely on and connect many drilling rods, after having bored a hole, necessary sectional dismounting drilling rod again, drill bit and the weight of drilling rod own are 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, 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.Because 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 comparatively other exploitation methods significantly improves, labor strength obviously improves, therefore, start to be applied preferably in nearest one or two years.But in fact, adopt the exploitation of this digging and transport unit also to there are problems.
First, due to comparatively large, therefore higher to the requirement of strength of material to the stressed impact of digging and transport machine middle girder, make complete equipment manufacturing cost higher, nonetheless, middle girder is still very 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 use heavy-duty motor that digging and transport machine could be driven to operate, and also must be equipped with control panel, transformer, strong switch, gearbox and cable etc. simultaneously, therefore, further increase the use cost of coal mining enterprise especially.And due to needs use heavy-duty motor driving digging and transport machine, so also easily there is the serious accidents such as cable leakage is hurted sb.'s feelings, initiation fire, especially for highly gassy mine, there is larger potential safety hazard especially.Again, during this digging and transport unit work, because digging and transport machine integrally operates, therefore for complicated condition, need the work plane adjusting length every now and then, compliance shows very poor.
In sum, how to realize half-edge coal seam fully-mechanized mining and be still in the exploratory stage, adopt the exploitation of digging and transport unit to be current more successful a kind of comprehensive mechanization production method, but still there is many weak points.
