深部煤炭资源探采对比与勘探方法探讨

Comparison of exploration and exploitation of coal resources and discussion on exploration methods

以淮南煤田口孜东井田为例,在探采对比分析的基础上,分析了其勘查技术方法选择的合理性,探讨了深部煤炭资源勘查技术方法。结果表明,两阶段的构造发育情况、煤层情况、开采地质条件、资源/储量基本吻合,说明针对上述问题采用的勘查技术手段是合理的,但在建井和生产时出现了巷道变形严重等问题,暴露了勘查过程中对地应力未进行测量,指出了深部煤炭勘查中要增加地应力的测量工作,才能更好地做到煤炭勘查为煤炭资源开发服务。

On the basis of the exploration and exploitation comparison, taking Kouzidong mining field as an example,the rationality of the exploration methods used in the exploration phase is analyzed, and the exploration methods indeep areas are discussed. The results indicate that the tectonic characteristics, the thickness and stability of the coalseams, the mining geological conditions, the resources/reserves results in the exploration phase basically agree wellwith the results in the exploitation phase. It turned out that the exploration methods used in exploration phase weresuitable. But there were some problems in the mining phase, such as serious tunnel deformation. It indicated theshortage of in-situ stress measurement in exploration phase. The paper pointed out it is necessary to strengthen thein-situ stress measurement in deep exploration to achieve the purpose to serve better the development of coal resources.
