The paper considers the expediency of complex processing of zeolite-smectite tuffs using the method of borehole hydro-mining. The basic information about deposits of zeolite-smectite tuffs in the Rivne-Volyn region of Ukraine and the main areas of their application in industry are presented. Also, the method of calculating the parameters of the process of hydraulic erosion of tuffs and underlying rocks by the method of borehole hydro-mining is given, and the dependence of the specific consumption of the working agent during erosion of tuffs and underlying rocks on the diameter of the nozzle at variable pressure is presented. The dependences for determining the rational forms of recess chambers with the specified erosion radius are given.

“…The existing relationship between the parameters of the development system [8,9], which provide the norm of reserves ready for excavation in a open-pit [10,11], determines, with a change in productivity for a mineral, a change in stripping ratios [12][13][14]. In turn, the change in stripping ratio is reflected in the volumes of rock mass and their distribution over the years of operation, which ultimately is one of the main factors affecting the economic indicators of a 1254 (2023) 012050 IOP Publishing doi:10.1088/1755-1315/1254/1/012050 2 open-pit mine [15][16][17].…”

The article studied the issue of improving the scientific and methodological base in the field of design and planning of open-pit mining by developing new and adjusting existing methods for determining the ore productivity of an open-pit, which should take into account the interconnection between the mining schedule and the productivity of an open-pit for ore, based on the condition for ensuring the standard volume of finished to the extraction of reserves. When choosing the production of an open-pit for ore, it is necessary to take into account the impact of the interconnection between the schedule of mining and production, based on the conditions of regulatory regulation of the volume of mining for the excavation of reserves, on the cost of ore mining and concentrate production. With an increase in ore productivity, the cost of ore mining, as well as the cost of production of concentrate reduction. At the same time, the very possible productivity of the open-pit for especially minerals is achieved, the economic efficiency of the development of deposits is achieved with the chosen direction of the open-pit. A decrease in productivity for a common mineral by 20 and 40% entails a decrease in profit from the development of the deposit by 10 and 20%, respectively. It has been determined that an increase in the slope angle of the working side of the open-pit significantly reduces the economic efficiency of the development of the deposit due to the fact that the operation of the open -pit with a large slope angle entails not only a decrease in the current stripping ratios as a result of an improvement in the mining schedule, but also a decrease in ore productivity, which reduces the present value of marketable products due to an increase in the period of development of the deposit. The results of the studies performed can be used by design organizations and mining enterprises in determining the ore productivity of an open-pit.

“…When developing a mineral, a large range of works is envisaged, which also includes the study of the properties of the mineral, the study of the stress-strain state of the field massif and other measures that ensure the most complete and efficient extraction of the mineral with the least losses for the environment [1][2][3][4][5][6][7][8]. However, when mining a mineral, both open and underground, there is a violation of the ecological balance and damage to the environment.…”

The purpose of the study is to select an effective methods and equipment for observing deformations in dangerous areas of the terrain, such as areas that are undermined by underground mining. It is known that the topical task of the mine surveying service is to improve remote sensing methods for the state of movement zones with craters, dips, cracks. The research methodology is based on the results of the performed analysis of methods for observing deformations using modern devices and technologies, and experimental work using the developed methodology, which provides for the combined use of digital methods and GPS technologies. Experimental work was carried out at the facilities of the Ordzhonikidze mine using various remote sensing methods, including those developed by the authors. The research used a design consisting of a digital camera and a GPS receiver. The performed analysis of the obtained survey results, using the proposed design of two devices, has shown its effectiveness in remote methods of observing the objects deformations located in areas undermined by mining operations. The scientific novelty of the results obtained lies in the methods development for remote observation of deformations of the ground's surface and objects, based on the structure use from a digital camera and a GPS receiver. This method was developed to increase the efficiency of performing research on objects deformations located in places that are dangerous for finding a person. The efficiency of using terrestrial digital stereo survey when the coordinates of the photographing points are determined with the help of GPS has been proved. The practical significance of the study lies in increasing work efficiency the on monitoring deformations of the earth's surface, buildings and structures located in areas dangerous for field work by traditional methods, which are performed using leveling and measuring the distances between the benchmarks of profile lines, which are usually used on areas undermined by underground mining. The use of terrestrial digital stereo photography with the coordination of photographing stations using GPS allows remote determination of the spatial position of the observed points with the required accuracy. Key words: ground stereoscopic survey, collapse zone, digital camera, GPS.
