薄煤层的厚度小,在正常倾角下煤层的垂直高度大大低于人的身高,人工开采或人工操作开采难度很大,所以发达国家普遍采用成套全自动采煤设备进行薄煤层无人操作开采。由于开采时各工艺已实现了全面自动化,无需矿工进入采煤工作面内进行相关设备操作,故这样的薄煤层工作面又称为全自动无人工作面或综合自动化无人工作面。
The thickness of thin coal seams is small. Under normal inclination, the vertical height of coal seams is much lower than human height. It is very difficult for artificial mining or manual operation. Therefore, in developed countries, the automatic coal mining equipment is generally used for unmanned mining of thin coal seams. Due to the fact that all processes have been fully automated at the time of mining, miners are not required to enter the coal mining face to carry out related equipment operations. Therefore, such a thin coal seam face is also called a fully automatic unmanned face or a fully automated unmanned face.
