摘要
充填钻孔作为矿山尾砂充填系统的核心通道,一旦发生堵塞,恢复难度大、成本高。因此,如何延长充填孔使用寿命已成为制约矿山尾砂治理、推动绿色矿山建设的重要挑战。钻孔偏斜率是影响充填孔套管寿命的最关键因素。因此,开展了小顶角高垂直度孔轨迹随钻监控与微拐点导向技术研究,同时研发了基于光纤光栅应变传感器的套管损坏实时监测系统,为提高充填孔成孔效率与质量,实现孔内套管损前预警与治理,延长充填孔寿命提供了有益参考和借鉴。
As the core passage of the mine tailings filling system,the filling hole,once blocked,is difficult and costly to restore.Therefore,extending the service life of the filling hole has become an significant challenge in mine tailings management and green mine construction.Borehole deflection is the most critical factor affecting the lifespan of the filling borehole casing.Research has been conducted on the technology of real-time monitoring of small top-angle and high-vertical borehole trajectory during drilling.Additionally,,a real-time monitoring system for casing damage based on fiber Bragg grating strain sensors has been developed.This provides a useful reference for improving the efficiency and quality of filling hole formation,realizing early warning and treatment of casing damage in the borehole,and extending the life of the filling hole.
