基于声波测井的采空区衍生灾害现场监测研究

西部矿山开采引发的大尺度采空区衍生灾害严重，现有的防灾和减灾理论与技术远不能解决，迫切需要深入研究灾害的发生机理、演化过程和控制技术基础，使矿业城市衍生灾害的影响和损失降到最低程度。采用声波测井等综合监测方法分析与评价采空区上覆围岩断裂高度、裂缝的发育情况及垮落岩块冒落状态，提高了观测结果的精度和可靠性，对大采空区衍生灾害有效控制、治理和定量化预报基础研究奠定理论依据。这将对西部少数民族地区的经济发展和促进我国工程科学的发展具有深远的意义。

Study on Sonic Wave Logging-based On-site Monitoring of Disaster Derived From Mined Area

The serious disasters derived from large mined area in the mining in western China are far from being solved by the existing disaster prevention and reduction theory. There is an urgent need to make a deep-going study on the disaster occurence mechanism, evolution process and control technology basis so as to reduce the effect and loss of the derived disasters in mining cities to a minimum. Using Comprehensive monitoring including sonic logging to analyse and assess the craking height and the development condition of fissure in the overlaying rock and the caved rock status in the mined area has improved the accuracy and reliability of the observation results, laying a theoretical basis for the basic study on the effective control, treatment and quantitative forcasting of the disasters derived from large mined area. This will be of far-reaching significance to the economic development in western China inhabited by the minority nationalities and to the promotion of China's engineering science.
