| 摘 要： | 通过对大竹坝井田构造复杂程度和煤层稳定程度进行分析研究和综合评价,认真总结煤层厚度变化的规律。对井田勘查工作进行了分区,在同一井田内划分了两个不同的勘查类型,选择主要的勘查区块进行了勘探,并按照论证的结论合理布设勘查工程间距,实现了以较小的经济投入获取较佳地质成果的勘查目标。其评价过程和由此获得的经济效益为今后的地质勘查工作中在确定地质勘查类型时有一定的借鉴作用。

| Abstract: | Based on studies and integrated appraisal on structural complexity and coal seam stability in Dazhuba coal field,the paper cautiously reviews changed regularity of coal beds thickness.Exploration zoning is made for the coal fields,there have two different kinds of prospecting divided in the same coal field,main explorative blocks are selected and explorative engineering grids are reasonably designed according to verified conclusion,which implement the explorative target of perfect geologic outcomes by small investment.Its appraisal course and corresponding benefits play a certain role for definition of explorative types in future. |
