We present the articles of the third issue of scientific journal "Mining Science and Technologyβ (Russia) for 2024:
Interesting studies have been conducted in the field of assessing the geotechnical stability of rock masses.
Using the calculated ratings, the rock masses of ore bodies and host sediments were evaluated for stability (classes/categories have been assigned), and the optimal method and parameters of workings support were determined. The geotechnical database accumulated during the research process provides the feasibility of calculating alternative ratings such as MRMR, RMi, GSI, etc., without the use of transient equations.
For more information, see the article:

The performed study allowed to develop a model of hyperbolic time-distance curve of GPR impulses reflected from a local feature located in a rock mass with an arbitrary number of layers. Practical application of the obtained results in studies aimed at automated determination of electrophysical properties of rocks and soils by hyperbolic time-distance curves will allow to create a database with up-to-date information on dielectric permittivity of rocks.

The next issue of the journal "Mining Science and Technology" (Russia)!
We present one of the problematic aspects of the articles in the new issue.
βοΈ How can the technological processes of drilling in hydrocarbon fields be improved?
New solutions to improve the quality of drilling in the Mesopotamian region of Iraq. Wells drilling and completion account for over 40% of all investments in the hydrocarbon energy industry. Reducing failures during the drilling process is one of the key prospects for increasing effective drilling time and addressing challenges faced during drilling and their consequences. The main types of complications in the wells drilling process include sticking of the drill string due to deviation, collapsing of unstable rocks, narrowing of the wellbore from crumbling rocks, absorption of drilling mud, gas-oil-water showings, and brine showings. Research conducted in the Mesopotamian basin of Iraq has revealed that there are technological solutions to improve the efficiency of drilling operations.
You can learn more from the review article, which will be published in the next issue before the end of this year.
This and much more is on the pages of our new issue!

π₯ How does the detonation velocity of explosives affect rock fracturing?
In quarries for building stone extraction, up to 30% of the rock turns into fines after blasting and crushing, reducing economic efficiency. One of the key factors is the prefracture zones formed during explosive detonation.
π¬ What was studied?
1οΈβ£ Explosive detonation velocity (ranging from 2 to 5.2 km/s).
2οΈβ£ Stresses in the rock mass during blasting.
3οΈβ£ Microfracturing using X-ray microtomography.
π Results:
βοΈ The size of the prefracture zone increases from 33R to 77R (where R is the charge radius) as detonation velocity rises.
βοΈ Microfracture density (N) depends on the distance from the charge:
β’ Near zone (10R): from 5,000 to 13,800 pcs/cmΒ³ (exponential growth).
β’ Far zone (70R): from 0 to 200 pcs/cmΒ³ (linear growth).
π‘ Practical conclusions:
β‘οΈ Using explosives with reduced detonation velocity minimizes prefracture zones and decreases fines yield.
β‘οΈ Optimizing blasting parameters allows controlled rock fragmentation and increases the output of marketable fractions.

How to Improve Block Stone Quality with Blasting Technology?
The extraction of block stone is a critical process in the construction materials industry, where maintaining the integrity of the material for further use is paramount. The key challenge lies in minimizing induced fracturing and surface roughness of the blocks.
πΉ Key Aspects of the Technology:
βοΈ Stress wave interaction β plays a decisive role in forming the main rupture between blastholes.
βοΈ Optimal charge parameters β blasthole spacing, blast product pressure, and linear charge density influence the zone of induced fracturing.
βοΈ Orientation of the rupture plane β aligning it with natural fractures in the rock mass increases the yield of high-quality blocks.
πΉ Research Findings:
βοΈNumerical modeling confirmed that adjusting charge parameters localizes the fracture zone.
βοΈReducing blasthole spacing while increasing charge size within limits ensures directional splitting.
