Bill spent several evenings with me in our bush camp in SW Tanzania where I was a geologist on a coalfield exploration job.
      


n recent years, neutron-neutron logging has been ugh widespeadly in coalfield exploration. In this paper, the correlation between the basic data of neutron-neutron lOgging and various data of the rock and coal quality determined in laboratory is analysed. The results of application of neutron-neutron lOgging data to the calculation of rock porosity, compressive strength, Brinen hardness factor, formation acoustic impedance,rock comPOnents and the size of rock grains are introduced in detail.

The paper mainly discusses the relationship between sulphur content in coal seam and the thickness of underlying sand body of 20 coal seams in Huoxi, Xishan, Pingshuo, Datong, Qinshui coalfields of Shanxi province, Zhungeer coalfield of Inner Mongolia and Yuxian coalfield of Henan province. By detailed analysis of superimposed position of isogram of sulphur content in coal seam and isopach of the thickness of underlying sand body, it is revealed that the peak value area of sulphur content is often situated on the areas where underlying sand bodies are thinner or pinch out. In other words, they are arranged in a staggered position. Among the 188 peak value areas of sulphur content from 20 pairs of isogram maps,8 are located in superimposed position with the peak value areas of underlying sand body in most part(4.26%);10 are partly located in superimposed position (5.32%);whereas 121 are located on the area of thinner underlying sand body (64.36%); and 49 are located on the pinch out area of the underlying sand body (26.06). It shows that the numbers of peak value areas of sulphur content, which are located on the thinner and pinch out parts of the underlying sand body make up 90.42%, so the staggered position between these two peak value areas is a general character with a reliability of 90%. Mean while, it is revealed that the isogram lines of peak value areas of sulphur content and underlying sand body often have concordant outlines, they are often in mosaic or parallel patterns. The control factor of these kinds of phenomena is the difference in the base relief of coal forming peat swamp determind by underlying sand body. Where the underlying sand body is thicker, the base relief is higher. In the lower area, in comparison with the higher area, commonly existed more underground or surface streams, which carried more fine suspending clays absorbing iron ions and calcium sulfate that would be reduced later and transformed to more pyrite. As a result of this process, the coal seam formed in the lower area contains much more sulphur than that formed in the higher area. This relationship can be used for predicting and searching for the coal area with lower sulphur content, and predieting the alternate tendency of coal seam's sulphur content in the process of coalfield exploration.

山西霍西、西山、平朔、大同、沁水、内蒙准旗和河南禹县煤田或矿区的煤层全硫峰值区常位于下伏砂体较薄带或尖灭处,呈错位关系,可靠性可达90%。其控制因素是下伏砂体决定的成煤泥炭沼泽基底地形的差异。下伏砂体厚时,沼泽基底常呈现较高地形;在砂体较薄或尖灭的低凹处,常由潜流或迳流带来较多含吸附铁离子的细悬浮粘土及硫酸钙,经还原作用可形成较多的硫铁矿硫,使低凹处形成的煤硫含量较高。这种关系可用来预测低硫煤区及勘探过程中硫含量的变化趋势
