厚覆盖区金属矿地震方法技术研究
|
摘要
在厚覆盖区,目前的勘查技术在探测深度和精度方面已不能满足深部资源勘查的需求,地震方法可用来弥补目前勘查技术在寻找深部隐伏矿方面的某些不足。由于金属矿区的地质构造十分复杂,金属矿勘查中的地震方法技术是一个十分复杂的课题。这里结合在甘肃金昌铜镍多金属矿区的试验研究,讨论了地震方法技术在厚覆盖区探测隐伏超基性岩体和控矿构造的试验应用效果。
The detecting depth and precision of the conventional prospecting techniques can not satisfied the demand of the deep resource exploration in deep coverage areas. And seismic method can be used to make up some shortages of the prospecting techniques in the survey of the deep hidden ore-bodies. Due to very complex geological structure in metallic ore areas, seismic method in base-ore metal exploration is a complicated question and this paper discusses the experiment and application effects of detecting hidden ultrabasic body and ore control structure with seismic method in deep coverage area combined with the experiment of Jinchang Copper-Nickel Polymetallic Deposit in Gansu province.
