摘要
综采面输送机的运行负荷是随着煤层倾角、煤层厚度、工作面长度、煤壁片帮情况、特别是采煤机割煤时的牵引速度以及采煤机在工作面的工作位置的不同而变化。多数情况下,综采面输送机是欠负荷运行,不能充分发挥其运输潜力;但短时间的超负荷运行又往往导致其被“压死”、断链等事故,严重影响工作面生产。本文提出的额定恒负荷运行法。可以充分发挥输送机的潜力,降低事故率,增加现有国产输送机的铺设长度,为进一步提高国产设备综采面的单产、效率提供了依据。
The running load of AFC in a fully mechanized face changes with such factors as, dip angle and thickness of coal seam, length of face, spalling of rib, especially haulage speed and position of shearer at face in coal cutting. In most cases, AFC is underload running, and its potential can not be brought into full play. However, short-term overload running always causes stalling of AFC or failure of chains and delay in production. The paper proposes a constant rated load running method, which will make full advantage of potential capacity of AFC, reduce the rate of breakdowns, increase the length of domestic AFC at face. The method also provides a good foundation for improving face output and efficiency.
