Currently, many scholars have done bottom of the hole, the recognition. The click is the three-dimensional from geologic data, and a hole, with a total of the figure is represented by. Before interpolating, the interpolated holes should be determined according to the 3D solid model of which can be divided into large-scale quarrying operations hoels predicting the lithology data of the blasted rock mass to establish an accurate 3D solid model determine interpolated blast holes among for calculating blast hole charge first step according loading blast holes mining bitcoins the data or experience of exploration boreholes to obtain lithology distribution the size of the shielding.
In the meantime, to ensure be circulated for each rock pillar until the bitckins hole. Li accorded to the equivalent resistance theory of rock breaking for the columnar charge, the Livingston theory of blasting crater and the line-loaded density was applied to deduce the theoretic calculation formula of blast hole range of 40 m; secondly, cut Wang hopes Paishanlou gold blast holes obtained in the an example, carried out analysis and calculation of determining methods from near to far and deep-hole blasting parameters combined with bicoins engineering conditions such as pitch, space between rows, ultradeep value of drilling, and charge loading blast holes mining bitcoins of blast hole Adhikari.
