滕北煤田武所屯井田武所屯断层新认识

根据武所屯煤矿煤16井下钻探和物探等资料，通过分析、对比地层岩性和厚度，对武所屯断层存在与否及其性质进行了探讨。结果表明：在武所屯下组煤16101工作面以西至井田边界，所探查范围内未见武所屯逆断层。对此存在三种解释：该断层垂向上自三灰向下逐步尖灭，未切割至煤16；原断层的走向不正确或前人认识有误；武所屯逆断层不存在。通过进一步查阅以往资料，并经过物探对比和剖面分析等手段，综合分析认为，在赵坡井田与武所屯井田之间的武所屯逆断层不存在，原地质资料认识有误。该研究结果对矿井增储、延长服务年限有重要意义。

New research findings on Wusuotun fault of Wusuotun mining field of Northern Tengzhou coalfield

According to the drilling and geophysical data obtained from 16th seam in Wusuotun coal mine, and based on the analysis and correlation of stratum, we discussed the existence and properties of Wusuotun fault. The result shows that the so called "Wusuotun reverse fault" couldn't be found in the detected area which extends from the west of 16101 working face to the field boundary. There exist possibly 3 reasons for this phenomenon, one is that the fault doesn't incised into the 16th seam, the second is that the original fault strike is not correct or the previous knowledge of the fault is wrong and the third is that there is no fault in this area at all. By consulting previous literature, by means of geophysical comparison and analysis of section, we consider that there does not exist reverse fault between Zhaopo mining field an Wusuotun mining field, so the original geological data is wrong. This study is significant to the increase of reserves and the lifetime extension of the coal mine.
