采金船采池渗透系数的确定

1 前言利用采金船开采砂金矿床时,形成一个有规则的采场,亦称采池。采金船是采选联合机械设备,漂浮在水面上作业,对采池的水深有一定要求,同时选矿用水也从池中抽取,在采金船生产过程中必须不断地向采池补充新水。为确定向采池供水的数量,首先应计算采池水的外渗量,向采池补充的水量应等于或大于外渗量才能确保采金船正常生产。渗透系数是计算采池水外渗量的重要参数,以前由于对采池的渗漏特点研究不够,在计算采池水外渗量时。

阐述了不同矿区及同一矿床不同地段的河流冲积砂金矿床底板坡度的特征 ,以矿区实例说明了由于存在底板坡度 ,故采金船选用不同的开采路线时 ,采池水的渗漏量相差较悬殊 。

Solar-Assisted Space Heating and Small Pond-Assisted Space Cooling of a Highly Insulated Energy Efficient House

For three weeks in October 2009, the U.S. Department of Energy hosted the Solar Decathlon Competition in which 20 teams of college and university students competed to design, build, and operate their own version of a solar-powered house. Team North＇s mission was to deliver North House, a compelling, marketable solar powered home for people with active lifestyles, while building Canada＇s next generation of leaders in sustainable engineering, business and design. This paper deals with a solar-assisted space heating system that was studied as a potential design for the competition. Among several other conclusions, it was found that using a solar-assisted in-floor heating system can decrease the energy consumption to only 8% of the case without the in-floor loop.
