某钾盐矿层形态变化原因和应对措施探讨

某钾盐矿床为海源陆相沉积成因矿床,其重要的找矿标志为"盐背斜"。也正因为盐背斜的存在,使整个矿床在形态上表现为面积大、矿层薄、起伏大的特点。随着地质工作的深入开展,矿体形态发生了较大的变化,并伴随着资源储量的较大变化,这给矿山的开发和规划造成了很大的不确定性。因此,提高矿体的可靠性,为井巷布设、矿山开发和规划提供准确的地质资料就显得尤为重要。通过对比历次地质工作成果,分析原因并提出应对措施。

The reason of the shape change of some potash ore bed and its countermeatures

The potash deposit is marine-originated and continental deposit,and the important prospecting indicator is ’salt anticline’.The area of the deposit is large,the ore bed is thin and the shape is complex just because of the salt anticline.The shape of the ore body changes greatly with the geological works going,as well as the resources and reserves.This makes the development and the planning of the mine uncertain.It is important to provide accurate geological information for the mine plan and layout and to increase the reliability of the ore body by analysing the results of former’s.
