Abstract:

To increase the amount of coal underground mining, labor productivity growth, reducing resource losses especially improving the level of safety and improving the working conditions of the employees, the promotion applies technical solutions advanced role in a technological scheme applied to mining coal seams with slope angle over 45° underground coal mines in Vietnam today but given the technical and economic indicators are relatively good and partly to meet production requirements but still limited as the cut and prepare large oven, labor productivity and yields are low coal mining,... etc reduce the effectiveness of the scheme operators technology. Meanwhile, anti-software platforms with flexible structures being applied in similar conditions in Chinese ZRY mines gave good results. Therefore, the need to study and apply this anti rigs to exploit coal seams with slope angle above 45° in order to improve yields, meet the requirements coal industry development
