深覆盖区找煤实践和方法研究:以商柘煤田为例
|
摘要
随着浅部煤炭资源的开发利用,越来越多的找煤重点在逐渐向深覆盖区转移。因此,在深覆盖区重视程度越来越高、难度越来越大的情况下,需要开展成矿规律研究和多元信息综合分析研究。要以二维地震工作手段为先导,以煤层底板等高线为基础,把各成矿要素相叠加勾绘而成,钻探工作和"三边"工作及时跟进。以现代成煤理论作指导,以地质研究为基础,采用各种先进的科学技术方法进行矿产调查工作,遵循由浅入深、由已知到未知、循序渐进的原则进行勘查工作。根据取得的一系列资料,综合一系列的成矿要素,编制勘查成果。
With exhausting of shallow coal resources,exploration and development of coal in deep coverage area became the reluctant choice.But,it is very difficult for coal exploration in deep.Therefore,a comprehensive analysis of multi-source information and study on mineralization pattern should be carried out before exploration.During exploration,firstly carries out two-dimensional seismic survey,then analyze various ore-forming elements based on the coal floor contour,finally the drilling and 'trilateral' timely follow-up.On the study of exploration method,the next principle should be followed: modern coal-forming theory as a guide,geological research as basis,advanced technology as a means,from surface to deep,from known to unknown,gradual and orderly conducting every process of exploration.According to a series of information obtained,a series of ore-forming elements should be comprehensively analyzed,then the preparation of report on exploration achievements.
