“…Calculations of drilling and blasting parameters were carried out according to the method [1][2][3][4][5][13][14][15][16][17][18][19][20][21][22][23] with a specific explosive rate of 1 kg/m³, inclined drilling of boreholes at an angle of 75°, a grid of boreholes 6×7 m. The volume of explosive dropping of rock directly into the dumping layer is insignificant (not more than 2-3%). Parameters of the internal dump are accepted as follows: the height of the first tier is equal to 30 m (on the recommendations of the Siberian branch of VNIMI institute) at an angle of its cutting is 40° (Fig.…”

In this article the rational value of overburden cut width and thickness of transportless overburden at mining of two dispersed flat seams IV-V and VI at Kureinsky section of Sibirginsky open pit mine are presented, which makes it possible to minimize the volume of rock re-excavation under the condition of the planned annual productivity of coal on the open pit and to ensure reduction of stripping costs. This task is complicated by the fact that the dip angle at the section is close to the limit on the condition of the possibility of spoiling of internal dump, and since the overburden rocks of the section are represented mainly by large-block sandstones on the clay cement and siltstones and their compressive strength is 60-80 MPa, then it is required to use a drilling and blasting method of their preparation for excavation. Under such conditions, optimizing the parameters of the transportless excavation scheme is of special importance for effective mining of the section.

“…A considerable number of works are devoted to the study of the parameters of transportless technology, in particular [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], where such issues as opening and excavation of stockpiled reserves, various cases for specific conditions, issues of drilling and blasting preparation of rock mass in the transportless zone, perspectives of technology using draglines and other issues are discussed. The technology of open-pit mining in the southern Kuzbass is not well-studied [16][17][18][19][20][21][22][23][24]. Below is a description and procedure for mining operations in the transportless zone of Krasnogorsky open-pit mine.…”

One of the methods of increasing the efficiency of dragline operation is to optimize their work when mining the end sections of the cuts. This is especially important when the length of the work front is relatively short. With mining operations going deeper, and the complication of mining and geological conditions of bedding, it often becomes necessary to mine shorter face sections. However, as a rule, design bureaus do not take into account and do not visualize excavation of end sections, because these are, in fact, special cases of standard excavation schemes. Nevertheless, it significantly complicates the organization of mining operations due to the need to create routes for draglines to ascend and descend to the dump tiers. Scientific literature does not pay enough attention to this issue due to its complexity and the need for a full-scale field experiment, which in modern conditions is often very problematic. This article establishes the relevance of the above-mentioned issue and identifies directions for further research.

“…Bird valley is a limestone quarry, but it is popularly known as 'Bird Valley Udyan' It was converted into a garden a few years ago and opened to the public as a recreational garden with boating and the walking track facilities. The main constituents of mine (quarry) waters are the waters coming from aquifers (the underground origin of water) and from the surface (atmospheric waters) (Yury Lesin et al (2018). Quarries could be used as a reservoir of water as they provide a large surface area for the collection of rainwater.…”

Purpose of the study: The purpose of this study is to make sure that the Bird valley’s quarry water is suitable for drinking purposes or not and to monitor the seasonal variations in the physico-chemical parameters of this quarry water. Methodology: Water samples from the quarry were collected in clean and sterilized polyethylene bottles. Water samples were collected from different points and mixed together to get an integrated sample. Some of the selected physico-chemical parameters of the quarry water have been analyzed. Results were compared with standard limits of IS: 10500-2012. All the parameters were analyzed in the laboratory by using standard methods and techniques. Main Findings: As per the obtained results this quarry water contains a very large number of Coliforms detected in the months of September and December and in June month Coliform count was 33 CFU/ml. This overall result for coliform is making this quarry water unfit for domestic purposes. Applications of this study: This study helps us to understand the current condition of this quarry water and also enables us to know whether the quarry water is fit for drinking purposes. It also enables us to know whether this quarry water can be used for domestic purposes after the treatment. Novelty/Originality of this study: Bird valley’s quarry water has not been analyzed from this point of view till date. This study will help us to understand the present condition of the water.
