摘要
为了给采掘工作提供详细的地质资料与煤层富水区分布情况,山西寿阳潞阳长榆河煤业有限公司定采用加拿大产PROTEM 67D瞬变电磁勘探系统,对需勘查地区进行勘查工作。在瞬变电磁法勘探工作中,运用高分辨反射系数法处理瞬变电磁勘探的资料,利用反射系数法参数进行资料处理和解释,提高瞬变电磁勘探的纵向分辨率,还可以一定程度上消除由于地形的变化对实测数据的影响。勘查数据推断出了区内8号煤层顶板及采空区富水区域位置、范围和形态,并对采空区含水性进行了评价,为煤矿安全生产提供可靠的水文物探资料。
In order to provide detailed Geological data and distribution of water-rich coal seam areas,Shanxi Shouyang Luyang Changyuhe Coal Industry Co.Ltd.has adopted the Canadian PROTEM67D transient electromagnetic exploration system to carry out exploration of the areas to be surveyed.In the exploration work of the transient electromagnetic method,the data of the transient electromagnetic exploration are processed by the method of high resolution reflection coefficient,and the data processing and interpretation are used by the parameters of the reflection coefficient method to improve the longitudinal resolution of the transient electromagnetic exploration.It is also possible to eliminate the influence on the measured data due to changes in terrain.The survey data deduced the location,scope and morphology of the water-rich area of coal seam roof No.8 and the goaf area in the area,and evaluated the water content of the goaf area to provide reliable data for the safe production of coal mines.
