摘要围岩集聚应力是诱发煤岩动力灾害的根本力源，为提高钻屑法表征围岩应力的精度和效率，基于理论分析和工程测试提出了通过钻孔极限摩阻力表征围岩应力分布特征的新方法。首先推导围岩应力与钻屑量的平面应力损伤方程，根据已有数值模拟、室内试验和工程测试结果验证该方程的有效性，并分析均布围岩应力、侧压系数、杨氏模量及损伤因子对钻屑量的影响规律；其次根据钻头受力特征，建立随钻参数与钻孔极限摩阻力的关系方程；最后基于自主研发的智能钻屑法钻车开展工程测试，采用75%的实测数据(共24组)建立随钻参数与钻屑量关系模型(DP-N模型)，并表征了12120工作面机巷围岩应力分布特征，通过25%的实测数据(共8组)验证了DP-N模型的有效性。研究结果表明：(1) 钻屑量与均布围岩应力和侧压系数均呈线性正相关关系，与损伤因子呈指数函数递增关系，与杨氏模量呈幂函数递减关系；(2) 钻孔极限摩阻力与钻屑量具有分段拟合特征，分段点两侧钻屑量随钻孔极限摩阻力的变化特征相反，且与煤体损伤因子和杨氏模量动态变化有关；(3) DP-N模型的围岩应力分布特征表征结果与实测钻屑量的表征结果基本一致，平均误差率为11.4%。研究结论可为煤岩动力灾害监测预警提供有效数据支撑。

Abstract：The concentrated surrounding rock stress is the fundamental force source to induce coal-rock dynamic disasters. To improve the monitoring accuracy and efficiency of the drill-cutting method，a new method to characterize the surrounding rock stress distribution characterization via borehole ultimate friction resistance is proposed based on theoretical analysis and engineering test. Firstly，the plane stress damage equation of the surrounding rock stress and drill-cutting weight is deduced，and the validity of this equation is verified by existing numerical simulation，laboratory test and engineering test results. According to the plane stress damage equation，the influence of uniformly distributed surrounding rock stress，side pressure coefficient，Young?s modulus and damage factor on drill-cutting weight is analyzed. Secondly，according to the force characteristics of the drill bit，the relationship equation between the drilling parameters and borehole ultimate friction resistance is established. Finally，the engineering test was carried out through the self-developed intelligent drill-cutting system. Combined with the test results，the relationship model between the drilling parameters and drill-cutting weight is established (DP-N model)，and the DP-N model is used to characterize the surrounding rock stress distribution characteristics of 12120 working face. The results show that：(1) The drill-cutting weight shows a linear positive correlation with the uniformly distributed surrounding rock stress and side pressure coefficient，an exponential function increasing relationship with the damage factor，and a power function decreasing relationship with the Young?s modulus. (2) The borehole ultimate friction resistance and drill-cutting weight have an obvious piecewise fitting characteristic. The drill-cutting weight on both sides of the piecewise point has the opposite characteristics with the borehole ultimate friction resistance，and is related to the dynamic changes of coal damage factor and Young?s modulus. (3) The characterization results of DP-N model are basically consistent with the characterization results of the measured drill-cutting weight，and the average deviation of DP-N model is 11.4%. The research conclusions can provide data support for monitoring and early warning of coal-rock dynamic disasters.
