滕县煤田张汪勘探区找煤可行性研究

通过对滕东预测区地层、构造、岩浆岩等地质条件的分析，论证了张汪勘探区3煤层赋存的可能性。根据3下煤层顶板砂岩分布特征，排除了同生冲刷作用对3下煤层的影响；区域构造对3煤层埋藏起到保护作用；根据岩浆岩在邻区的分布，分析了岩浆侵入对3煤层的影响；利用南沙河勘探区、田陈井田、许楼井田钻探资料，推测了本区3煤层厚度，估算煤层埋深在-1200m以浅、-1200～-1500m的资源量合计15950万t，有单独建井的前景，建议进一步开展工作，为煤炭资源的开发提供准确的地质资料。

Feasibility Study on Look for Coal in Zhangwang Exploration Area,Tengxian Coalfield

Analyzed geological conditions of stratigarphy, structure and igneous rock etc. in Tengdong predicting area, demonstrated hosting possibility of No.3 coal in Zhangwang exploration area. According to No.3lower roof sandstone distribution features, put aside the impact of syngenetic washing process to No.3lower coal; regional structure protected burying of No.3 coal; according to neighboring area igneous rock distribution, analyzed igneous rock intrusion impact to No.3 coal. By the use of drilling data in Nanshahe exploration area, Tianchen and Xulou minefields, speculated thickness of No.3 coal in the area and estimated total 159.5 million tons of coal resources above -1200m and -1200～-1500m in the area, thus a prospect to construct a coalmine independently. Further works are suggested to provide veracious geological data for coal resource exploitation.
