Ultimate Guide To Air-Core Drilling

One of the most preferred drilling and exploration method is aircore drilling for its accuracy in deep exploration ability. This approach provides a good choice to heavy drilling machinery as it works in ensuring an optimal drilling comfort and sample collection. When choosing a drill type, it is wise to consider some economic factors and their sample evaluation approach. The article is designed to provide you with some basics on the air core drilling approach. Its benefits in both exploration and sample evaluation, as usual, mine life and economic value, play a major role in determining the mining profit. All

Guide To Quality Sample Drilling

To ensure the stability of the wall during Quality Sample Drilling and the bottom of the hole, where necessary, a coil of coating pipes or a fluid generally consisting of a mixture of water and bentonite (in a percentage of 3-5%) is used. Bentonite is a very plastic volcanic clay. The bentonite mud is characterized by a volume weight slightly higher than that of water and by thixotropy, or by a very high viscosity in a state of rest and much less in the state of motion. These characteristics make the bentonitl mud particularly suitable not only for supporting the
