Subdrill distance – extra drilling length to add to each hole. Spacing – the distance between holes in a row. Pattern – a set of blast holes which will be collectively drilled, sampled, charged, and blasted.Īn example of a pattern is shown below. A lot of the terminology used in this document is specific to the mining and quarryingĭrilling parameters that you can customise include:Ĭollar – the starting point of a drill hole.ĭiameter – the diameter of drill hole in units of measure (that is, metres or feet).ĭip – the angle of a hole above or below the horizontal. Terms are the same in all countries, and you might need to apply your preferred terminology in someĬases. There are several terms and concepts specific to this tutorial that are explained in this chapter. Note: These workflows demonstrate the steps in this tutorial. Patterns, along segments, or in a straight line between any two points digitised in Graphics.īefore you begin this tutorial, you must have:Ī good understanding of the basic Surpac concepts of strings, segments, DTMs, and The drill and blast functions allow you to create and charge vertical and inclined holes in rectangular Task: Load sample intervals into a database
