深部开采地表沉陷预测与控制存在的问题及对策探讨

Probing into problems and countermeasures about prediction and control of surface subsidence mining in Deep-lying

随着我国煤炭资源的开采向深部延伸,带来了地表沉陷预测与控制等主要技术难题。在深部开采条件下,结合地表沉陷的特点,总结分析了预测与控制存在的主要问题,表现在其预测模型、参数以及保护煤柱的留设方法和参数等方面。针对存在的问题,提出了深部开采条件下,应深入开展基础理论研究,重视地表移动观测等相关研究工作。

In China, with coal resource mining in deep lying being developed, therefore, the main technology problems about prediction and control of surface subsidence are brought out. In the conditions of mining in deep-lying, combining with the characteristics of surface subsidence, main problems of prediction and control are summed up and analyzed. Which is the concentrated expression of prediction model and its parameters, protective coal pillar designed method and its parameters. According to these problems, some relative researches are proposed, it is important to study basic theory research, surface and overlying strata movement observation and so on.
