建筑物下安全开采深度的观测试验研究

Research of observed test on safety exploiting depth of mining under buildings

本文从安全开采深度的概念出发,通过对地表移动观测站试验分析,说明建筑物下开采时存在安全开采深度,且对于不同的采矿地质条件,安全开采深度均存在,但安全开采深度值不同,解决三下采煤特别是建筑物下采煤的安全开采问题提供技术依据。

In this paper, Starting from the concept of safety exploiting depth, through analysing surface displacements observation station test, this article has confirmed the safety exploiting depth exist while mining under buildings, and has also shown that the safety mining depth even exist in different mining geological, but the values of safety mining depth are different. These conclusions have also supplied technical evidence for solving the problem of safe working of three unders in coal mining especially mining under buildings.
