航空磁法测量在新疆某煤矿火烧区圈定中应用效果分析

Application Effect Analysis of Aeromagnetic Survey in Delineation of Burning Area of a Coal Mine in Xinjiang

为积极响应国家政策,整合利用资源,贯彻安全生产的基本原则,测区煤层自燃、形成火烧区,对井巷建设存在安全隐患,测区煤层因构造作用倾角较大,为查明测区内火烧区范围、埋深及空间展布状态,采用航空磁法测量物探方法查明火烧区范围、埋深及空间分布特征,初步圈定两层煤存在火烧现象,分别为下_(5)、下_(10)煤层,通过欧拉反演大致确定火烧区深度范围,航空磁法测量在本区取得了良好的勘查成果。

In order to actively respond to national policies,integrate and utilize resources,and implement the basic principles of safe production,the spontaneous combustion of coal seams in the survey area forms a fire area,which has potential safety hazards for shaft and roadway construction.The dip angle of coal seams in the survey area is large due to tectonic action.In order to find out the scope,buried depth and spatial distribution of the fire area in the survey area,aeromagnetic survey geophysical method is used to find out the scope,buried depth and spatial distribution characteristics of the fire area,It is pre⁃liminarily delineated that there is burning phenomenon in two layers of coal,namely lower 5 and lower 10 coal seams.The depth range of the burning area is roughly determined through Euler inversion.Aero⁃magnetic survey has achieved good exploration results in this area.
