摘要
通过现场实测,获取特定地质开采条件下的裂缝带发育高度,建立适合本地条件的数学模型,对实测数据进行反演分析,运用FlAC-3D进行数值仿真模拟,模拟结果真实可靠,用于对类似条件下的开采覆岩破坏高度进行预计,可以大大降低生产成本。
With the site measurements, the height of the crack zone development was obtained under the special geology and mining conditions and the mathematic model suitable for the local conditions was established. An inversion analysis was made for the measured data. An numerical simulation was analogized with Flac3D. The simulation results were accurate and reliable. The simulation can be make to predict the failed height of the overburden rocks due to mining with the similar conditions, which could highly reduce the production cast.
