4.TYPOMORPHIC CHARACTERISTICS OF MAIN ROCK-FORMING MINERALS IN TIN - BEARING PORPHYRIES, YANBEI, JIANGXI
5.Ore dressing practice of altered rock type of gold-bearing ores in Shang-Gong Gold Mine and its prospects
7.The result shows: the stress state of rock-bolt can be improved by grouting surrounding rock; combined whole section bolting-shotcreting-grouting support can improve the stress distribution, and can decrease the size of plastic zone in surrounding rock, resulting in a loop bearing structure near by the periphery of roadway and the long-term stabilization of the surrounding rock.
8.The gem-grade beryl, topaz and rock crystal are occurred in the well differentiated hypermiarolitic Be-bearing granitic pegmatite.
9.A very hard, dense, even-textured, silica-bearing sedimentary rock used in whetstones.
