“…), timely reclamation, and operational techniques (field planning, the use of advanced technologies and irrigation methods, the organization of optimal operating modes of irrigation and drainage systems, carrying out desalination measures, maintenance groundwater levels, etc.) [10][11][12]. The republic's territory has specific soil and climatic conditions; due to insufficient natural drainage and a high level of groundwater mineralization, a number of territories are "primarily saline".…”

For the conditions of Uzbekistan, it is necessary to maintain the reclamation condition of irrigated lands constantly and increase soil fertility. It is necessary to study the land reclamation condition in our region. An important factor is that collector-drainage waters are used for irrigation to pay off the shortage of water resources. The object of the study is the collector-drainage waters formed in the Republic of Uzbekistan. The article presents research on the method of statistical data processing, materials analysis, field research, and computer plotting curves and diagrams. As a result of the irrational use of collector-drainage waters, secondary clogging is observed in some areas. Data analysis was carried out from 2005 to 2020. The analysis of long-term studies shows that by 2020 there was a decrease in highly saline lands, which makes 83 thousand hectares. Whereas in 2005, saline lands made up 160 thousand hectares. Also, data analysis shows that areas with different mineralization are almost unchanged and need to develop scientifically based measures. The purpose and objectives of scientific research are to study irrigation with collector-drainage waters, their impact on the reclamation state of irrigation lands, and assess their suitability for irrigation. To increase the reliability of assessments of the quality of collector-drainage waters under various natural and economic conditions, it is recommended to use the relationship between water mineralization and the ratio of chlorine to sulfate. The dependence was built on the results of long-term data on the hydrochemical regime of collector-drainage waters. Estimates of our research have shown that at least 50% of the collector-drainage runoff is suitable for use in places of formation in Uzbekistan. Collector-drainage waters have mainly a sulfate type of salinity, and such waters with mineralization of 2-3 g/l, such waters with mineralization of 2-3 g/l can be used for repeated irrigation. To cover the shortage of irrigation water, drainage waters with increased mineralization by diluting them with fresh water will also be used for reuse.

“…The controlling influences are labor protection measures aimed at achieving the lowest possible levels of morbidity of workers. These measures can improve working conditions, compensate for the damage caused by adverse impacts, contribute to the protection of workers, regulate their work and rest regime [14].…”

“…Assuming that after carrying out a set of optimal measures, the minimum possible levels of morbidity will be reached after some time, we take this time for the forecasting period [11]. Having estimated by expert means the values that the parameters of working conditions will have over time (without carrying out optimal measures), using the identification model [1] we will determine the real forecast of morbidity indicators [14]:…”

The paper is devoted to the analysis of the extent of injury in the coal mine by age categories of employees. Different age groups of employees are studied. Measures taken to protect workers by types of productive activities in coal mines aimed at improving working conditions in the workplace are proposed. Due to the proposed measures the decrease of level of injury and occupational diseases of workers was achieved.

The article presents the results of a multi-factorial experiment to justify the parameters of a rotating sprayer. Optimization of the parameters of the pneumatic disk atomizer shows that with the correct choice of the specific liquid flow rate (qi), disk radius (r) and the number of radial channels (η r) at a constant air flow rate, it leads to obtaining the required median-mass droplet diameter. Therefore, when justifying the diameter of sprayed drops, it is necessary to consider a combination of the specific flow rate of the liquid and the radius of the disk. To obtain a monodisperse spray of drops with a median-mass diameter d= 80…120 µm, the disc radius should be in the aisles r=75.8…83.4 mm, the specific liquid flow rate qi= 0.61…0.96 l/min and the number of radial channels for pairs of disks in the aisles η p = 4.59… 5.75 things.
