随着采矿技术的强化以及开采深度的不断增加,自然通风已不能解决采场大气的污染问题,因此采场的空气含尘量不仅显著增大,而且严重影响到矿工的健康和采矿运输设备的正常工作。防尘早已成为露天采煤发达国家普遍关心的问题。
With the strengthening of mining technology and the continuous increase of mining depth, natural ventilation can not solve the problem of atmospheric pollution in the stope. Therefore, the dust content of stope in the stope is not only significantly increased, but also seriously affects the health of miners and the mining equipment normal work. Dust prevention has long been a common concern in the open coal mining countries.
