采金船开采的砂金矿床,开采的坡度是个重要条件。目前,适合我国现有采金船开采的砂矿床坡度究竟多大,或者说超过多大坡度就不能用采金船开采了,还没有见到权威说法,只是一般地说产地平坦或坡度不大。为了使采金船开采顺利进行,对于适合采金船生产的砂矿床坡度必须有个准确说法。根据罕达汽金矿1964年以来的十七年采金船生产实践,现有采金船能开采的最大坡度为50‰。它是由实际水上最大采掘高度与实际最小采幅宽的比值决定的,也要考虑到尾矿溜槽,皮带机架不发生拖阻。各型号船
Gold mining gold mining gold deposit, the mining slope is an important condition. At present, suitable for China’s existing gold mining gold mining sand slope just how much, or more than the slope can not be used gold mining, have not seen the authoritative statement, but in general that the origin is not flat or gradient. In order to make the mining of gold mining vessels proceed smoothly, there must be an accurate statement about the slope of the sand deposits suitable for the production of gold mining vessels. According to the 17-year mining operation of gold mining vessels since 1964, the maximum gradient of the existing gold mining vessels is 50 ‰. It is determined by the actual ratio of the maximum mining height and the actual minimum width, taking into account the tailings chute, the belt rack does not occur drag. All types of boats
