高德矿增大水砂充填供水能力的研究

The Study of Raising the Ability of Water Supply Of the Hydraulic Backfilling in Gaode Mine

因充填供水管年久失修,管径相对缩小,供水能力降低,充填能力不够,严重影响矿井生产。本文论述了在不停产条件下,改造充填供水管,增加充填能力的措施及实施后的效果。

Because a large amount of incrustation attachs to the shell of water supply pipe the inside diameter, becomes small, therefore, the ability to su-pply water decreases and so does the ability of the hydraulic backfilling. As a result production is seriously affected.This paper presents a method with which to increase ability of water supply of hydraulic backfilling system in normal prodution condition and the result is given as well.
