PROCESS FOR FLUID DRAINAGE AND COLLECTION BY IN-SITU LEACHING INVOLVING DIVERSION HOLES |
摘要 |
<p>A process for fluid drainage and collection by in-situ leaching involving diversion holes. The process comprises the following steps: 1) arranging within an ore body multiple fluid collection paths (1); 2) arranging close to the bottom of the path on both sidewalls of each path multiple diversion holes (2), the fluid collection paths and the diversion holes forming a multi-channel control plane for fluid drainage and collection of a pregnant solution; arranging in each fluid collection path a blocking wall (3), connecting the frontal lower part of the blocking wall via a conduit (4) to an opening of the path, controlling the conduit at the outlet with a ball valve (6); 4) by releasing pressure, forming a high pressure gradient between the ore body and the engineering control plane, thereby forming a multi-channel pregnant solution collection system. The process allows a reduction in the pregnant solution loss rate, and environmental pollution.</p> |
