摘要
煤矿的开采过程易造成围岩变形,引起一定裂隙,且随着导水裂隙带的发育,容易对煤矿的安全产生影响。鉴于此,采用仿真分析的形式建立数值模型,对围岩变形引起的导水裂隙带发育规律进行分析,从而为煤矿的防治水提供指导,保证煤矿的开采安全。
The mining process of coal mine is easy to cause surrounding rock deformation and certain fractures. With the development of water diversion fracture zone, it is easy to affect the safety of coal mine. In view of this, a numerical model is established in the form of simulation analysis to analyze the development law of water diversion fracture zone caused by surrounding rock deformation, so as to provide guidance for water prevention and control of coal mine and ensure the mining safety of coal mine.
