Study On Exploration And Exploitation Comparison About The Condition Of Coal Resources In Guoyang Mining Area

Coal is our country’s main energy which has renewable characteristics. Therefore, how to improve the resource recovery rate is very important. Doing well in the prospecting contrast has important significance in directing the mine production, reasonably using the resources and improving mining rate of resource. And it also has the instruction function to the productive supplementary exploration of coal mining area.This paper does a statistical analysis on the stoping and exploration of the geologic information in Liudian coal mine and Guobei coal mine, and obtains the the average and exploratory actual thickness of the coal in Mining Area103and104at Liudian coal mine and Mining Area1at Guobei coal mine. By comparison and analysis, the average actual thickness of the coal in Mining Area103and Mining Area1are less than the exploratory average thickness in there; and the average actual thickness of the coal is greater than the exploratory average thickness in Mining Area104. This paper does a qualitative analysis of the effect on thickness variation of coal bed by the scouring action of fault, fold and roof sandstone.Through analyzing and discussing of the3D seismic data and the stoping of the geologic information in Liudian coal mine and Guobei coal mine, and using the break points with the drop height in each kilometer being equal or greater than5meters as the evaluation index, we can obtain the contrastive differences of the fault structure. Among them, the break points in stoping process of Mining Area103and104at Liudian coal mine are approximately same with which in the3D seismic exploration, and the difference value is0.17. The contrastive differences of the break points in Mining Areal and2at Guobei coal mine is large, the break point in the actual production condition is1.79, while the the break point in the3D seismic exploration is0.8.Based on the fractal theory, we divide the Liudian coal mine and Guobei coal mine into101block sections. Using fault fractal dimensions as the evaluation index, we make a quantitative evaluation on the development degree of the the break points with the drop height being equal or greater than5meters in Liudian coal mine and Guobei coal mine. According to the relationship between the development degree of fault structure and the fractal dimension value, we divide the development degree of fault structure into four levels, and finally obtain the zone map of fault development degree. Studies of fractal dimension value of the3d seismic break points with the drop height being equal or greater than5meters and the fault break points with the actual production condition less than5meters found that the drop height less than5meters in each kilometer will also increase with the increase of the fractal dimension of faults.Figure [28] table [27] reference [45]...
