小煤窑采空积水区的探查方法
|
摘要
为了解决开采下组煤层受上组煤层采空积水区的影响,往往需要对上部煤层采空积水区的位置、范围、积水量进行探查清楚,减少不必要的钻探工程,精准确定探放上部煤体钻孔的施工参数,为准确解放开采煤层提供可靠的地质基础资料。在走访曾经在小煤窑工作的相关人员、通过查阅小煤窑遗留下的相关资料和地方志的基础上,采用井筒见煤点推断测算法、地面瞬变电磁法和地震法相结合的物探探测方法,对小窑不明采空积水区的位置、积水量以及受积水影响区域进行了研究。结果表明:该方法适合不明采空积水区的探查治理。
In order to solve the problem that the lower coal seam is affected by the upper coal seam water area, it is often necessary to explore the location, scope and water volume of the upper coal seam goaf area, reduce unnecessary drilling engineering, and accurately determine the construction parameters of the upper coal seam drilling, so as to provide reliable geological basic data for the accurate liberation of the mining coal seam. On the basis of visiting relevant personnel who worked in small coal mines and consulting relevant materials and local chronicles left by small coal mines, a geophysical exploration method is proposed, which combines the shaft coal point inference and measurement method, ground transient electromagnetic method and seismic method, to study the location, volume of water and the affected area of water. The results show that this method is suitable for the exploration and treatment of the water accumulation area in the unknown mined-out area.
