两点测应变法在确定潜孔钻力－凿深曲线中的应用引言钻头－岩石界面联系对凿岩机计算具有极其重要的意义。对于给定的钻头、岩石及加载条件，其主要特性是力－凿深曲线。根据力－凿深曲线及凿岩系统其他参数，可用简单的分析法￣［１，２］或数量模拟￣［３，４］来确定凿...
Application of Two-Point Strain Method in Determining Down-hole Drilling-Depth Curve Introduction The drill-rock interface connection is of great significance to the calculation of rock drill. For a given bit, rock and loading conditions, the main feature is the force-depth curve. According to the force-chisel curve and other parameters of the rock drilling system, a simple analysis method [1, 2] or numerical simulation [3, 4] can be used to determine chiseling ...
