辛安河金矿200HS型采金船于1988年建成,是我国第一条胶带溜槽主选的200L采金船。投产后发现该船开采的矿体内大粒金、粗粒金含量较多,经过地质调查,该矿体粒度14～22mm的矿砂中金品位可达到矿体平均品位。而原设计的主选设备为18条胶带溜槽,该设备给矿粒度上限为-15mm,实际给矿粒度-14mm。为充分回收黄金资源,避免大粒金白白流失,经过认真细致的可行性研究,初步设计、施工图设计及审查,在1991年初采金船大修中,对200HS采金船部分主选设备进行了改造。
Xin’anhe Gold Mine 200HS gold mining vessel was built in 1988, is China’s first tape chute 200L gold mining vessel. After commissioning, it was found that large gold and coarse gold content in the ore bodies mined by this ship were more. After geological survey, the gold grade of the ores of the ore body with the grain size of 14-22 mm can reach the average ore grade. The original design of the main election equipment for the 18 tape chute, the equipment to mine the upper limit of -15mm, the actual grain size to-14mm. In order to fully reclaim the gold resources and avoid the loss of large grains of gold, careful and meticulous feasibility study, preliminary design and construction drawing design and review were carried out. At the beginning of 1991, some main selection equipment of the gold mining vessel was transformed .
