【摘要】 钻头是直接破碎岩石的工具。钻头类型通常用岩石可钻性级值的大小来选择。文中选用数据组合处理方法 (GMDH)建立岩石可钻性与各岩石力学特性参数的函数关系 ,编制了该方法确定可钻性的计算机软件。文中给出了计算实例。通过试算表明 ,该方法运算简便 ,结果可靠 ,可用于计算岩石可钻性。更多还原

【Abstract】 Bit is the tool of crushing rock directly.The value of rock drillability is usually used to select the type of bit.The self-organization method(GMDH)is studied to build the relationship between rock drillability and the rock characteristic parameters.The computer program is complied and practice example is given.The results are showed that the method is simple,results are satisfactory and GMDH can be used to calculate the rock drillability.更多还原
