根据目前金刚石冲击回转钻进法日益推广的需要,本文从模拟的观点出发,提出了一种测定岩石可钻性的新型便携式仪器。该仪器结构简单,具有多种功能,可进行回转或冲击回转钻进法的可钻性测试及钻进规程的模拟,也可用来测试岩石研磨性。通过对仪器性能的检测,提出了相应测试方法和操作规范。用它进行金刚石钻进岩石可钻性的测定,所得结果与实际吻合。最后提出了研磨性测试方法。
According to the needs of increasingly popularizing diamond impact rotary drilling, this paper presents a new type of portable instrument for measuring rock drillability from the viewpoint of simulation. The instrument has a simple structure, a variety of functions, can be rotary or impact rotary drilling drillability test and drilling procedures simulation, can also be used to test the rock grindability. By testing the performance of the instrument, the corresponding test methods and operating specifications are proposed. It is used to determine the diamond drillability of rock drilling, the results obtained are in line with the actual. Finally, the abrasive test method is proposed.
