摘要
为实现对招贤煤矿开采沉陷区域动态周期的全方位监测,解决区域地表沉降等问题,综合采用SBAS-InSAR技术及快速静态测量方法,进行了地表沉降信息提取及现场实际测量。数据分析结果表明:招贤煤矿井田沉降区域分布呈现明显的规律性,地表最大累计沉降量为89.42 mm,总沉降区域面积约2.227 km^(2),沉降量较大的区域面积约0.4764 km^(2),沉降主要集中在1302、1303、1304、1305、1307工作面;与快速静态测量法观测的数据进行对比分析可知,通过SBAS-InSAR技术分析沉降数据的精度可达亚厘米级。研究详细且深入地剖析了不同时间段内,该塌陷区地表沉陷的幅度变化情况,精确量化了各阶段的沉陷变化,并清晰展现了在空间维度上的分布特征,全面揭示了招贤煤矿井田地表塌陷区的沉陷动态变化规律,明确了不同区域随时间推移在沉陷表现上的差异以及整体的发展趋势。
In order to realize the comprehensive monitoring of the dynamic period of the subsidence area of Zhaoxian Coal Mine and solve the problems of regional surface settlement,SBAS-InSAR technology and rapid static measurement method are comprehensively adopted to extract the surface settlement information and field actual measurement.The results of data analysis show that the subsidence area distribution of Zhaoxian Coal Mine presents obvious regularity.The maximum accumulated subsidence of the surface is 89.42 mm,the total subsidence area is about 2.227 km^(2),and the area with large subsidence area is about 0.4764 km^(2),which is concentrated in the working face of 1302,1303,1304,1305 and 1307.Compared with the data observed by the rapid static measurement method,it can be seen that the accuracy of SBAS-InSAR technology can reach sub-centimeter level.The research analyzed in detail and depth the amplitude changes of surface subsidence in the subsidence area in different time periods,accurately quantified the subsidence changes in each stage,clearly displayed the distribution characteristics in spatial dimension,and comprehensively revealed the dynamic change law of surface subsidence area in Zhaoxian Coal Mine field.The differences in settlement performance and the overall development trend of different regions over time were clarified.
