薄煤层前进式开采在国内较少,尤其是机采和采空区膏体充填、运输为刮板机、转载机及支护一体化的采煤设备布置和方法在国内尚属首例;煤层在0.5～1.8 m,运输巷道配置带式输送机、转载机,随着煤层的变化,采面的底板与运输巷的底板高差在不断变化,为此,将刮板机机头机尾的电机、减速机方向采用垂直工作面型式并且将机头和机尾放置上下两巷内加装液压自动调高装置,以适应煤层变化的采煤、支护、充填、运输。
Advance mining in thin coal seam is less in China, especially for the filling and transportation of paste in machine-mined and goaf, and the layout and method of coal mining equipment integrated with scraper, loader and support are the first in China. Coal seam In 0.5 ~ 1.8 m, transport lane configuration belt conveyor, reloader, with the coal seam changes, mining floor and transport lane floor elevation difference is constantly changing, for this purpose, the scraper machine nose tail The direction of the motor and reducer adopts the vertical face type and the head and tail are placed in the upper and lower two laneways to install the hydraulic automatic height adjustment device to adapt to coal mining, support, filling and transportation under the change of coal seam.
