摘要
利用钻探、物探及化验等多项成果,采用标志层、煤岩层组合特征、煤质特征和测井响应等多种方法,对安鹤煤田当中岗勘查区含煤地层进行划分对比,首次确定了煤系含煤12层及各组、段厚度,确定主采的二1、一11煤层的层位,二1煤电阻率372 ～1350 Ω·m,低灰低硫,一11煤视电阻率320～860Ω·m,高灰高硫.并以当中岗勘查区为例,论述煤岩层对比的重要性及不同方法的适宜性,结合对比数据,阐述该区煤系沉积成因、组合差异、物性差异等内在机理.
Abstract
The reconnaissance and general survey results,such as drilling,geophysical prospecting and chemical testing results,and the methods of key beds,interlayer spacing,coal quality analysis and log response,were applied to divide and compare the coal-bearing stratum of Dangzhonggang Exploration District in Anhe Coalfield.The 12 layers of coal containing coal measure strata were determined,so was the thickness of the group or member.And the horizon of key workable coal seams B1 and A was determined.The apparent resistivity of coal seams B1 was 372 ～ 1350Ω · m,coal seams B1 was low ash low-sulfur coal.The apparent resistivity of coal seams A11 was 320 ～ 860Ω m,coal seams A was high low ash high sulfur coal.Taking Dangzhonggang reconnaissance area as example,the importance of coal and rock contrasting and the suitability of different methods were discussed,the area coal sedimentary origin,composition differences,differences in the physical properties inherent mechanism were analyzed,combining with comparative data.
