| 1 | The Huanren Pb-Zn ore deposit in Liaoning Province, abounding with rich lead, zinc, copper and iron, is recognized as skarn type. | |
| 2 | With the main technique problems be discussed, the proper qualification and procedure for black start of huanren power plant are proposed. | |
| 3 | Compared with the original design of the reservoir flood operation, it shows that the real-time operation method can increase the hydropower generation benefits without bringing any more flood risk. | |
| 4 | The feasibility of which short-hole shrinkage method is used for mining of low-grade and submarginal ores in Huanren Mine is demonstrated in this paper. | |
| 5 | With classification of rock types, test of metal elements and other geologic characteristics, the regularity of the horizontal and vertical zonation of the ore bodies and rocks is analyzed. |
