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。
The geological reports of Puxi and Futai Xiajing use qualitative methods to divide the structural complexity and the stability of coal seams, and the results are biased. Analyze the cause and the influence of the deviation, and put forward the scheme of quantitatively dividing the structural complexity and the stability of the coal seam. In the process of dividing resource reserves, according to the provisions of “Coal and Peat Geological Prospecting Standards” and “8.2.1 ”, the principle of block division is proposed: including the conditions of direct control, circumscribed area and circumscribed area, and How to understand and divide the blocks in different situations is discussed. At the same time, it provides the method of dividing blocks into single holes, multi-wires, single holes per lane and revealing sporadic non-recoverable sections.
