摘要
在白银公司深部铜矿东部特厚富矿体成功地应用了分段空场嗣后充填法,实施多种地压控制措施,保证了中稳凝灰岩条件下20m大跨度空场稳定,达到了强采强出的目的.
The experiment was performed succeessfully on the sublevel open stoping and subsequent filling for eastern extra-thick rich orebody in Deep Copper mine, Baiying Nonferrous Metals CO,many measures of earth pressure control were used, thus the sta-bility of open stope with a span of 20m under condition of moderately stable tuff was en-sured, and the intensified mining and ore removal were achieved.
