摘要: 以服务于煤矿生产监测监控以及科学研究的钻孔为研究对象,以用于应力测量的钻孔为例进行分析,依据Kirsch推导结果,确定钻孔选取直径时不宜大于钻孔许用直径;根据计算推导结果,分析钻孔直径选取范围主要受钻孔受力状况、围岩力学性质以及安装条件的影响因素,以此提出钻孔参数选取原则。同时,这种钻孔参数的选取方法为其他监测监控以及科学研究设备仪器的研究开发提供理论参考。

关键词: 钻孔直径, 钻孔应力计, 钻孔许用直径

Abstract: Taking monitoring for the coal production and boreholes for scientific research as subject,cases for boreholes of stress measurement are analyzed.According to the Kirsch derivation results,it is determined that the selected drilling diameter should not be greater than the permission.The calculation results indicates that the range of drilling hole diameter are mainly affected by factors of stress state of borehole,the mechanical properties of the surrounding rock and installation conditions,so as to propose the principle of selecting drilling parameters.At the same time,the selection of drilling parameters provides a theoretical reference for research and development of other monitoring devices and the equipment and instruments for scientific research.

Key words: Drilling diameter, Drilling stress meter, Allowable drilling diameter
