Konya CJ (2003) Blast design in rock blasting and overbreak control The same results were validated using Random forest method wherein the model R 2 was 0.9791 and RMSE was 0.8799.ĬL Jimeno EL Jimeno FJA Carcedo YV Ramiro De 1995 Drilling and blasting of rocks, geomining technological institute of Spain Rotterdam Netherlands AA Balkema From the field trials, it was evident that the use of low-density emulsion can help in reducing the back break and optimise the overall cost of the blasting process. For the random forest model, R 2 0.9791 and RMSE 0.87899 and for linear regression was R 2 was 0.824 and root mean square error (RMSE) 0.72, respectively. The variables used for the study was such as burden to spacing ratio, stemming to hole-depth ratio, p-wave velocity and the density of explosive. In this paper, an attempt is made to predict back break using the random forest method. Therefore, predicting and subsequently optimising back break shall reduce their problems to some extent. Due to improper free face created from the previous blast and the presence of loose strata in the face increases the overall cost of production. It can cause rockfall during drilling due to the cracks present in the in situ rock mass at the perimeter. It does not help in creating a smooth high wall and free face for next blasting due to cracks, overhang and under-hang. Indeed, you should expect random forests to be slower than neural networks.Back break is an unsolicited phenomenon caused due to rock condition, blast geometry, explosive and initiation system in mines. The constant term omitted with the $O$ notations can be critical. The speed will also depend on the implementation, the $O$ just gives information about the scalability of the prediction part. The comments are quite accurate, to summarize (and calling $p$ the number of simulateneous workers you have) the complexities should be (depending on the implementations) :
