工作面导水裂隙带高度观测分析
|
摘要
工作面回采后上覆岩层遭到破坏,下沉形成导水裂隙,导水裂隙带高度的确定对于顶板水害的防治具有重要的意义。文中首先对导水裂隙带高度观测系统工作原理及系统构成进行了阐述,其次对回采工作面垮落带和弯曲下沉带理论计算分析,最后将导水裂隙带高度观测系统运用到回采工作面导水裂隙观测实践。研究结果表明导水裂隙带高度观测系统可以有效的确定工作面上覆导水裂隙带高度,实测结果对指导该矿防治顶板突水具有重要的参考意义。
The overlying strata are destroyed after the working face, and the subsidence is formed to form the water guide fissure, and the determination of the height of the water guide fissure zone is of great significance to the prevention and control of the water damage of the roof. In this paper, the working principle and system composition of the height observation system of water conducting fracture zone are first described.Secondly, the theoretical calculation and analysis of the caving zone and the bending and sinking zone of the mining face are analyzed. Finally,the water guide fracture zone height observation system is applied to the observation practice of water guide fissure in the mining face. The results show that the height of the water fissure zone on the surface of the working face can be determined effectively by the height observation system of the water conducting fracture zone. The measured results have important reference significance for guiding the prevention and control of the roof water inrush of the mine.
