The Hoeryong Coal Mining Machine Factory has recently manufactured a hydraulic comprehensive coal cutter of a new style that is expected to contribute to developing the coal-mining industry.
This year the factory has pushed ahead with the production of the hydraulic coal cutter, while striving hard to fulfil the production plan of the mining machinery that is nearly five times as high as last year.
And they applied efficient jigs and other devices to process the parts and accessories for the machine as required by the designs.
In this way they have developed the coal cutter in an original way.
The structurally simple cutter can be easily operated with much less manpower, materials and electricity. As the mobile machine is in conformity with the local conditions, it draws the attention of coal miners.
The units that have already adopted the cutter require no longer blast materials and increase their daily output more than twice. Meanwhile, their consumption of manpower and props has been cut off by 50% and 33%, respectively.
