黑龙江省含煤盆地分布与煤炭资源地质调查工作方向

Coal-bearing Basin Distribution and Coal Resources Investigation Orientation in Heilongjiang Province

在总结以往地质工作的基础上,对黑龙江省含煤盆地工作程度、区域地质概况、含煤地层等进行分析,认为黑龙江省主要成煤时代为中生代和新生代,受滨太平洋构造影响,构造形态为北北东向的三隆三坳,聚煤作用以断陷带内为主。以此将全省划分为6个主要聚煤带,97个含煤盆地,其中优先选择33个盆地,分为18个区块作为今后的调查方向,并提出相应的工作重点、原则、方法及主要工作量。

Based on past geological exploration works, analyzed exploration degree of coal-beating basins in Heilongjiang Province, regional geological general situation, coal-beating strata, considered that the marginal-Pacific tectonic domain affected the formation of alternating 3 uplifts and 3 depressions during coal-forming ages, coal-accumulating process was happened mainly in faulted depressions and 6 main coal-accumulating zones were divided, Based on present degree of investigation, selected 33 basins among 97 coal-beating basins and further divided into 18 sectors as investigation orientation henceforth. Corresponding key emphasis, principle, method and workload were put forward in investigation works.
