涡阳矿区煤炭资源条件探采对比研究
|
摘要
煤炭具有不可再生的特点。在现有技术条件下,如何提高资源采出率显得尤为重要。搞好探采对比,对指导矿井生产、合理利用资源、提高资源采出率均具有重要意义。
论文通过对刘店矿、涡北矿回采地质资料和勘探地质资料的统计分析,得出刘店矿103采区、104采区、涡北一采区实际平均煤厚和勘探平均煤厚。通过对比分析,刘店矿103采区和涡北一采区实际平均煤厚小于勘探平均煤厚；104采区实际平均煤厚大于勘探平均煤厚。本文定性的分析了断层、褶皱以及顶板砂岩的冲刷作用对煤层厚度变化的影响。
通过对刘店矿、涡北矿三维地震资料与回采地质资料的分析研究,以每Km长度上出现落差大于等于5m的断层断点数为评价指标,得出断裂构造对比差异。其中刘店矿103采区和104采区回采过程中的断点数为与三维地震勘探的断点数大致相同,差值为0.17。涡北矿一采区、二采区断点数对比差异较大,实际揭露的断点数为1.79,而三维地震勘探的断点数为0.8。
利用分形理论,将刘店矿和涡北矿共划分了101个块段。以断层分维值为评价指标,对刘店矿和涡北矿落差大于等于5m的断层发育程度进行了定量评价。根据断裂构造发育程度与分维值之间的关系,将井田断裂构造发育程度分为四个等级,并最终得到断层发育程度分区图。对三维地震落差大于等于5m断层的分维值与生产揭露落差小于5m的断层断点数研究发现,随着断层分维值增大,每km长度上出现落差小于5m的断层断点数也随之增大。

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.
