长城窝堡井田煤系地层沉积环境分析

Analysis of great wall wobao well field coal formation stratumde positing environmental

为了确定长城窝堡井田沉积类型及其沉积环境的演化过程,应用沉积学理论通过对长城窝堡井田区域地质、地层的岩性、沉积构造、古生物化石和煤系分布规律等因素进行综合分析研究,从而确定了该地区为滨浅湖沉积类型及其沉积环境的演化过程;并为该井田煤层的赋存规律性的认识,开采方案的确定、储量挖潜等工作提供了理论依据;最后,根据这一成煤理论,推测了张强盆地内其它可能聚煤区域,为该区域煤炭资源进一步勘探提供了新的靶区。

In order to infers the Great Wll wobu well field area deposition type of this area and deposition type and the deposition environment evolutionary process, though synthesis analysising and researching the factor of the Great Wall wobao well field area geologic structure, stratum rock nature, depositin structure, ancient biological fossil and coal bed distributing rule, thus this article infers that the deposition type of this area is shallow lake and lake shore depositing type and the deposition environment evolutionary process; and provides the theory base to understand the coal bed existence regulation, determinat mining plan and estimates the reserves： at last, according to this producting coal theory, infers to other area where can product coal in Zhangqiang basin, provides new target area to coal mine investigation in this area.
