This review paper examines extraction methods in the dimension stone industry. Traditional techniques, like thermal shock, hammer and chisel, and plug and feather, were used historically. However, advancements in technology have led to the adoption of mechanized methods. Diamond wire cutting is a highly efficient technique that reduces waste and ensures quality. Challenges like high costs and wire breakage remain. Circular diamond saws and frame sawing are explored as alternative methods. Stone characteristics influence machinery selection and researchers have studied the impact on extraction efficiency. Controlled blasting with explosives shows promise and requires further exploration and optimization.

H13 is a tool steel with good strength to thermal cracking, and resistance to wear, and erosion. It is extensively employed in the manufacture of molds and dies. Because of its hardness, it is challenging to manufacture with traditional methods, and damages the surface during cutting, which lessens the effectiveness of components. Recently, laser cutting has become a possible method for achieving high rates of material removal. The use of laser cutting to manufacture complicated forms is a contemporary development in laser technique. The drilling on 0.44 mm thick H13 by 100 m fiber laser rays is highlighted in this study. Entropy using COPRAS is employed to optimize fiber laser settings for the drilled hole. Response surface analysis is utilized to determine correlation of fiber lasers process parameter and ANOVA validates the model. Further, ANN is used to predict the experimental results. In the current research, the laser’s output power, scanning speed, and duty cycle are all taken into account. The results of the tests revealed that laser power is the most important element affecting the quality of drilled holes. The optimum condition of COPRAS grade offers 4.27 µm of roughness, 89.89 µm of heat impacted zone, 139.595 µm of overcut, and 0.074113 mm of material removal rate. The observed and predicted figures are relatively near to each other, according to the experiments. The outcomes of the confirmation test (PO = 5 W, SOS = 10 mm/s, DC = 25%) demonstrate that optimal conditions provide greater surface precision than initial trails.

in coAL seAms BAseD on roughness AnALysisThe occurrence of faults in coal seams has an impact on the possibility of methane hazard. There are several methods for identifying tectonic faults, but they cannot be applied directly to solve dynamic hazard problems in coal mine. Thus, searching for appropriate methods, that can detect faults in regional and local scales is needed. In order to meet this need, the paper proposes a new measurement method of estimating changes to the coal structure, based on profilometry measurements (roughness analysis) and application of madogram functions. based on examining coal samples from near fault zones it was shown that the proposed approach allows us to detect changes of the coal surface that appear as the distance to a tectonic fault gets shorter. The proposed method, due to its simplicity and speed of measurement, implies a potential for practical application in the process of detecting local tectonic dislocations in coal mines.
