“…More particularly the zone where the deposit is located given the compactness of the gray to beige limestone rock which does not allow the infiltration of rainwater in depth, hence the non-existence of sources of outlets on the flanks and at the foot of the deposit. The rocky massif of the bouzitoune quarry, is part of the north-eastern massifs of the Constantine neritic series [15,16].…”

Purpose. To find a relative methodology which will help the systematic analysis of the parameters influencing the blasting plan and a better understanding of the mechanisms of fragmentation of rocks with explosives. Methodology. The approach uses the Kuz-Ram model to predict blast performance. Three models were used to consider the effect of blast plan geometry on the quality of blast rock fragmentation. A new blasting plan is proposed using the Langefors method and the Kuz-Ram empirical model. The results obtained were compared with those of previous blasts. Findings. The research results show that the optimal fragmentation of 89.2 % with a balance between fine particles of 5.7 % and outsized blocks of 5.1 % of rocks by explosive in the Heliopolis aggregates quarry is highly dependent on the type and quantity of explosive used, the direction of initiation, and the cracks caused by the waves of shock (back effects). Originality. The present work is concerned with the problem of the quality of rock blasting which will ultimately affect the costs of drilling, blasting and the efficiency of all mining operations. Parameters influencing the processes of rock fragmentation during mining operations are specified. Practical value. The purpose of blasting is to disaggregate the material in order to facilitate its recovery by the extraction equipment. It is therefore necessary to correctly define the blasting plan by optimizing these geometric parameters, the nature and the quantity of explosive, the initiation sequences aim to have the right particle size distribution.

“…To identify groundwater potential zones, some studies have combined the GIS and RS with the multicriteria decision-making (MCDM) models (Saaty 2008;Aneesh and Deka 2015;Singh et al 2018;Maize et al, 2020). A few of them are the fuzzy logic (Mallick et al 2019), certainty factor (CF) (Razandi et al 2015), weighted overlay index (Prasad et al 2008), probabilistic models such as frequency ratio (FR) (Thapa et al 2017;Das and Pardeshi 2018;Braham et al 2022), multi-influencing factor (MIF) (Acharya et al 2019); machine learning (Saha et al 2022), and analytical hierarchy process (AHP) (Agarwal et al 2013;Ajay Kumar et al 2020;Arshad et al 2022;Aissaoui et al 2023). It is found that the use of the AHP model via GIS is an efficient and effective technique for the spatial data management, and also utilized to identify groundwater potential zones.…”

This study aims to demarcate groundwater potential zones using an integrated approach of remote sensing, geographical information system, and analytical hierarchy process in a reservoir-induced seismicity (RIS) region of western India. Multiple important factors affecting groundwater such as geology, geomorphology, soils, land use and land cover, slope, lineaments density, drainage density, rainfall, normalized vegetation index, and topography wetness index were considered for deciphering the groundwater potential zones. Spatially distributed thematic layers of all these factors were generated using remotely sensed data and ground-based field data in GIS platform. The assigned weights of all these layers and their attributes were then normalized by using analytical hierarchy process technique. The deciphered groundwater potential zones of this RIS area were categorized as very good (15.68%), good (27.34%), moderate (29.25%), poor (19.54%), and very poor (8.19%). These assessed groundwater potentialities were positively correlated with the specific yields of actual field data with a correlation coefficient of R = 0.90, and was found reasonable. It was also observed that the very good to good potential zones were in the upstreams. Most of the very good groundwater potential zones (~ 16.79%) were found in the northern part, namely Koyna region (which was more the seismically active) than the Warna region (~ 14.57%) located in the southern part. It indirectly indicated that the groundwater potentially also induced the seismicity of earthquakes along with both Koyna and Warna reservoir waters. The deciphered groundwater potential zones in this RIS area will aid in better study of the earthquake seismicity in future.

“…In this Special Issue, Aissaoui et al (2023) in their study propose a methodology to identify the most suitable areas for groundwater recharge in the Middle Seybouse subcatchment in Guelma, North-East Algeria. They produced a map showing 60% of the investigated area has very high potential aquifer recharge and used receiver operating characteristic curve to validate it.…”

As climate change is growing, water security becomes an urgent challenge in the Middle East and North Africa (MENA), the most water scarce region in the world (World Bank, 2018; UN Water, 2020). Algeria is one of these countries under large stresses (Kwasi & Cilliers, 2020). The water stress index is poor with a water availability ratio of 411 m3/cap/year. Forecasts estimate a value of 300 m3/cap/year in 2050 (Falkenmark et al., 1989; Kherbache, 2020). Although, the natural factors (climate change) affect the access to water and lead either to severe water shortages and regional disparities, the water deficit is mainly due to a lack of sustainable groundwater management associated to poor knowledge of the resource (PNE,2010; Kherbache, 2020) [...].
