| 摘 要： | 浦溪、富台下等井田地质报告中采用定性方法划分构造复杂程度与煤层稳定程度，其结果存在偏差。分析偏差致因及产生的影响，提出了定量化划分构造复杂程度与煤层稳定程度的方案。在划分资源储量块段时，根据《煤、泥炭地质勘查规范》“8．2．1”条款，提出了块段划分原则：包括直接控制范围、外连范围、外连范围划定条件，并对不同情况下如何理解和划分块段进行了探讨，同时提供了单线单孔、多线但每线单孔及巷道揭露零星不可采区段情况下的块段划分方法。

| Abstract: | Because of qualitative divisions of structure complexity and coal seam stability were used in geological reports of Puxi and Futaixia minefields caused deviation in results. Analyzed the causation and adverse effects on results, put forward a scheme to divide structure complexity and coal seam stability quantitatively. During resource reserve block division, based on the ＂8.2.1＂ clause of the ＂Coal, Peat Geological Exploration Criterion＂, put forward principle of block division including： directly controlled range, outer association range, outer association range demarcation. Discussed how to comprehend and divide blocks under different conditions. Meanwhile provided block division methods under conditions of single line single borehole, multiple lines but single borehole on every line and roadway disclosed fragmentary unmineable sections. |
