YunTao Expansion Exploration Of The Handan Areas Coal Deposited Law Research

To find out the coal layer and its texture of the deposit properties and the main factors for Yun(enlarged area of Yun Jialing coal field)Tao(enlarged area of Taoer coal field)expansion of the Handan areas,and to speed up the exploitation of deep coal resources, the paper has applied the method of trend surface to analyse the main coal layer 2~# mine deposit law and the development law of coal layer structure within research and its impact on coal mining,and to changes of coal have been studied, are divided into two mining areas north and south, were respectively discussed.Result showed:The deposited property of 2~# coal mine is relatively stable in northern West of Yuntao expansion of the Handan areas. The change law of coal thickness is that thick in the north and south sides, which is thin in the middle, and which east is magmatic intrusion area, coal layer was engulfs and less thinner, which results in large areas of non-mining area; The thickness trend of 2~#coal in the south area is gradually increased from north to south and from west to east, and the southern growth is faster than the northern; The change of coal seam thickness is subjected to the control action with magma intrusion and sedimentary structures. Fold is less developed in northern mining area, mainly in the form of fault-based structure, towards trend are mostly NNE, and are both high-angle normal fault, the fault is still south of the main geological structures, accompanied by a number of east-west axis of the Was "W" type of simple-relief folds.Coal quality of 2~# main coal seam in Yun jialing coal field is anthracite,belongs to medium ash,extra-low volatile matter and low sulfur coal,the main sulfur is organic sulfur,the ash content on the palne thickness change in north and south, middle thin,sulfur content from the north to the south,gradually increased from east to west; Coal quality of 2~# main coal seam in Taoer coal field is anthracite, belongs to medium ash,extra-low volatile matter and extra-low～low sulfur coal,the main sulfur is pyritic sulfur,the ash content and sulfur content on the plane both gradually increased from south to north.The two magmatic activity are strong within the mining area, the structure becomes more complex, results a greater impact on coal mining; penetrated into the coal seam, the seam structure becomes complex, thinner thickness, worse admissibility, harder variation rank(mostly anthracite), the local metamorphy become natural coke and graphite.
