Description
Technical field
The present invention relates to a kind of coalcutters for exploiting in underground coal mine, and in particular to a kind of anti-wall caving coalcutter.
Background technique
Coalcutter is to realize one of coal production mechanization and the important equipment of modernization.Mechanical coal mining can mitigate body
Power labour improves safety, reaches high yield, high efficiency, low consumed purpose.Double-ended shearer combines domestic and international bog-head coal
The successful experience of layer coalcutter is the novel high-power low seam mining machinery for being directed to China's specific national conditions and designing, therefore by
It welcomes.
But it there is problems:
1) some mines need timely and effectively supporting to handle in goaf after mining, increase activity duration and expense.
It is 2) big to support apparatus pressure since the coal wall after exploitation is vertical with roof and floor as mining depth is continuously increased,
And coal wall is easily-deformable under action of underground, is easy to cause underground stope and tunnel occurrence of large-area side falling accident.
In view of this, being badly in need of providing a kind of raising operating efficiency, extends the service life of support apparatus and can exploit not
With the anti-wall caving coalcutter of coal quality situation.
