基于动态测量的煤矿地表开采沉降观测研究

Subsidence observation of coal mine surface mining based on dynamic measurement

随着煤炭采掘活动不断向深部延伸,高强度的采掘活动引起的地表沉降问题日益严重,对地表的建构筑物、公路、铁路等构成了威胁,为了最大限度地保护矿区地面村庄、交通设施、建筑、水体等不受地表沉降损害,研究煤矿开采引起的地表沉降移动规律及科学的观测方法显得尤为必要。本文基于动态测量技术,通过对比选择适宜的测量方法,对山西某矿10903工作面对应地表开采沉降进行了深入的观测研究,得到了大量的动态数据,并利用Origin软件对数据进行了处理分析,最终形成了沉降区域的三维视图,为类似地质条件下地表沉降的整体研究提供了参考。

With the continuous extension of coal mining activities to the deep, the problem of ground subsidence caused by high strength mining activities is becoming more and more serious, which poses a threat to the construction, highway, railway and so on. In order to protect the ground villages, transportation facilities, buildings and water bodies of the mining area to the maximum extent, the study of the coal mine The movement rule and scientific observation method of surface subsidence caused by mining are particularly necessary. Based on the dynamic measurement technology, this paper makes a thorough observation and Study on the surface mining settlement of coal mine in shanxi by comparison and selection, and obtains a lot of dynamic data. The data are processed and analyzed by Origin software, and finally the three-dimensional view of the subsidence area is formed, which is similar to geology. The overall study of surface settlement provides a reference.
