四川省XXX磷矿区布设沿脉工程的尝试

EXPLORATION DESIGN OF PRE-MINING AREA FOR A PHOSPHATE MINE IN SICHUAN

四川XXX磷矿位于扬子准地台西部著名的川滇成磷带。磷矿赋存于寒武系下统麦地坪组中段。地质条件简单,矿层分布稳定。邻区有已勘探开发的同类型磷矿。鉴于此,为满足业主工程进度的要求,采用在首采区布设沿脉坑道工程,作为加密勘探工程,为矿区首采区开采设计提供依据。

The XXX phosphate deposit in Sichuan lies in a famous Sichuan-Yunnan mineralization belt which belonged into the west of the Yangtze paraplatform. The phosphate ore bed occurs within the Maidiping Formation of lower Cambrian system and it is persistent. The geology in the area is not too complex then the neighborhood exploration and development have been the same type of phosphate. In order to meet the requirements of the owners, and to ensure the progress of the project, we＇re planning to lay gopher drifts in the pre-mining area as a infill work to get more basic data for desian.
