| 中文摘要: |
| 南方某硬岩型铀矿山棉花坑矿井200 m中段43线的充填井，由于靠近构造带，其围岩较破碎，再加上含水量大，因而贯通地表的安全条件差，普通天井掘进法难以应用.为此，采用深孔分段爆破成井技术掘进该充填井.本文介绍了采用深孔分段爆破成井技术掘进该充填井的方案设计和施工技术. |
| 英文摘要: |
| The shaft for backfilling in the 43 exploratory line on the 200 m level in the Mianhuakang mining area in a hard rock uranium mine in South China could not be excavated by using conventional shaft sinking methode since it was near the fault zone and the rock around it was broken and water- bearing.Therefore,the shaft was excavated by using deep hole blasting.This paper presented the design for the blasting and the construction. |
