摘　　要：白银深部铜矿在露天坑下部高应力环境下试验了大跨度空场嗣后充填采矿法。为控制采场地压，设计了合理的采场结构参数和特殊的采场回采顺序，采用了光面爆破、锚索加固、快速充填等技术措施，从而确保了试验的成功。The test for the wide span open stoping with subsequent fill in a high stress environment below the opencast pit was made in Deep Copper Mine operated by Baiyin Nonferrous Metals Co. In order to control the earth pressure in the stopes, the suitable stope structure parameters and the special stoping sequence were designed, and the technical measures such as smooth blasting, cable anchoring and quick filling etc were taken, so the successful test was ensured.
