Project risk management in the mining industry is necessary to identify, analyze and reduce uncertainty. The engineering features of mining enterprises, by their nature, require improved risk management tools. This article proves the relevance of creating a simulation model of the production process to reduce uncertainty when making investment decisions. The purpose of the study is to develop an algorithm for deciding on the economic feasibility of creating a simulation experiment. At the same time, the features and patterns of the cases for which the simulation experiment was carried out were studied. Criteria for feasibility assessment of the model introduction based on a qualitative parameters became the central idea for algorithm. The relevance of the formulated algorithm was verified by creating a simulation model of a potassium salt deposit with subsequent optimization of the production process parameters. According to the results of the experiment, the damage from the occurrence of a risk situations was estimated as a decrease in conveyor productivity by 32.6%. The proposed methods made it possible to minimize this risk of stops in the conveyor network and assess the lack of income due to the risk occurrences.

The subject of traditional institutions cannot be undermined in the project of sustainable leadership and good governance in Nigeria given the locus and crucial role of the institution in the past and modern Nigeria. It is incontrovertible that traditional and aboriginal values are held highly with reverence and respect in virtually all parts of Nigeria. To discountenance their relevance will be too costly in any leadership-cum-governance discourse. Towns, villages and cities were duly recognized and protected as the harbingers of culture, mores, norms and values. The contemporary government structure in Nigeria duly recognizes the importance of traditional institutions by having a Commission for Local Government (LG) and Chieftaincy Affairs at all State levels. Moreover, 5% of allocations to LGs go statutorily to the tradition institution in the State. Hitherto, the recklessness and abuse of the native authority system of local government administration in the 1950s–60s had led to the moderation and reforms of the system, which has continued to affect traditional institutions to date. To this end, the paper argues that traditional institutions hold so much values and cohesive practices as well as socially integrative potentials for nation-building so much that the State can leverage on them for sustainable leadership and overall good governance. The methodology adopted for collecting data for this study is descriptive research method, which relies on primary direct observation (eye-witness) account and relevant secondary materials such as texts, journal articles, official documents and internet materials. The data collected were analyzed and presented using thematic analysis and tables. National and international data already analyzed were found essential to drive home the argument of this study. The outcome of the paper provides useful information on how traditional institutions serve as a veritable platform for sustainable leadership and good governance in Nigeria. The paper concluded that traditional institutions, with its rich culture, values and practices, possess sufficient merits to propel the country towards sustainable leadership that would concomitantly induce economic, technological and political growth in Nigeria.

Nowadays, the scale of graduate education in our country has been growing, but the quality of graduate education has not been improved. Therefore, how to effectively improve the quality of postgraduate education has become the most concerned issue in the academic circle and universities, which directly highlights that the internal guarantee mechanism of postgraduate students to improve the quality of postgraduate education has become the focus of academic research, in which tutors are the main influencing factors of postgraduate education quality. The tutor plays a positive and dominant role in stimulating, demonstrating, modeling, guiding and infecting the postgraduate's behavior. This paper analyzes the existing problems in exerting the role of postgraduate tutors, and from the problems, puts forward the countermeasures and suggestions to exert and mobilize the initiative of tutors.

Primary school students are in a period of rapid development of thinking. Primary school mathematics is particularly important for the cultivation of students' abstract thinking ability. The section of number and algebra is the most basic and important content in mathematics. This paper takes number and algebra as an example to analyze the abstract thinking ability of primary school mathematics and its training strategies, so as to provide some practical guidance for teaching.
