Intelligent unmanned mining is a key process in coal mine production, which has direct impact on the production safety, coal output, economic benefits and social benefits of coal mine enterprises. With the rapid development and popularization of 5G+ intelligent mines and coal mine intelligent equipment in China, the intelligentization of intelligent unmanned mining has become an important research topic. Especially with the promulgation of some Chinese policies and regulations, intelligent unmanned mining technology has become one of the key technologies of coal mine production. To understand the connotation, status quo and development trends of intelligent unmanned mining, this paper takes the relationship between key technologies and engineering application of intelligent unmanned mining in China as the perspective. It is proposed that the intelligent unmanned mining technology is in the whole process of working face mining. A research structure of unmanned follow-up operation and safe patrol is changing to the mode of intelligent adaptive mining, followed by the basic concepts and characteristics of intelligent unmanned mining. Relevant researches that maybe beneficial to the proposed research content are reviewed in four layers, which include basic theory, key technology, mining mode, and overall design system theory and technology. Finally, the current intelligent unmanned mining mode and future trends in this field in China are summarized.

Over two million tonnes of fertiliser are applied to New Zealand pastures and crops annually and there is an increasing desire by farmers to ensure that the best possible economic return is gained from this investment. Spreading distribution measurements undertaken by Lincoln Ventures Ltd (LVL) have identified large variations in the evenness of fertiliser application by spreading machines which could lead to a failure to achieve optimum potential in some crop yields and to significant associated economic losses. To quantify these losses, a study was undertaken to calculate the effect of uneven fertiliser application on crop yield. From LVL's spreader database, spread patterns from many machines were categorised by spread pattern type and by coefficient of variation (CV). These patterns were then used to calculate yield losses when they were combined with the response data from five representative cropping and pastoral situations. Nitrogen fertiliser on ryegrass seed crops shows significant production losses at a spread pattern CV between 30% and 40%. For P and S on pasture, the cumulative effect of uneven spreading accrues, until there is significant economic loss occurring by year 3 for both the Waikato dairy and Southland sheep and beef systems at CV values between 30% and 40%. For nitrogen on pasture, significant loss in a dairy system occurs at a CV of approximately 40% whereas for a sheep and beef system it is at a CV of 50%, where the financial return from nitrogen application has been calculated at the average gross revenue of the farming system. The conclusion of this study is that the current Spreadmark standards are a satisfactory basis for defining the evenness requirements of fertiliser applications in most circumstances. On the basis of Spreadmark testing to date, more than 50% of the national commercial spreading fleet fails to meet the standard for nitrogenous fertilisers and 40% fails to meet the standard for phosphatic fertilisers.Keywords: aerial spreading, crop response, economic loss, fertiliser, ground spreading, striping, uneven application, uneven spreading, yield loss

Coal Mine Methane

Increasing emissions from mining areas and a high global warming potential of methane have caused gas management to become a vital challenge. At the same time, it provides the opportunity to obtain economic benefits. In addition, the use of combined heat and power (CHP) in the case of coalbed methane combustion enables much more efficient use of this fuel. The article analyses the possibility of electricity production using gas engines fueled with methane captured from the Budryk coal mine in Poland. The basic issue concerning the energy production from coalbed methane is the continuity of supply, which is to ensure the required amount and concentration of the gas mixture for combustion. Hence, the reliability of supply for electricity production is of key importance. The analysis included the basic characterization of both the daily and annual methane capture by the mine’s methane drainage system, as well as the development of predictive models to determine electricity production based on hourly capture and time parameters. To forecast electricity production, predictive models that are based on five parameters have been adopted. Models were prepared based on three time variables, i.e., month, day, hour, and two values from the gas drainage system-capture and concentration of the methane. For this purpose, artificial neural networks with different properties were tested. The developed models have a high value of correlation coefficient. but showed deviations concerning the very low values persisting for a short time. The study shows that electricity production forecasting is possible, but it requires data on many variables that directly affect the production capacity of the system.

Agroforestry Practices

The present paper highlights the importance of hedgerows and enclosures in the mountains of Central Spain. Now, these landscapes have suffered profound variations in terms of agroforestry practices, especially in the Mediterranean mountains where the characteristic multifunctional has largely been lost. The article analyzes land uses changes, dynamics, and their morphological features between the first half of the 20th Century (1956) and the second decade of the present time (2019). The paper was divided into three sections. First, the identification of land uses using orthophotograph and aerial photograph; after that the info was checked with fieldwork. Eleven categories were identified according to the dominant use and land use changes and size of land parcels were taken into consideration. Second, the configuration and the information collected through the type and intensity of change in land uses made it possible to recognise and quantify their distribution and trend between these two dates. Also, the kernel density algorithm available in the Arcgis 10.5 software was used to obtain density and changes in land parcels. Finally, an overview is given of the main role that this agroforestry plays due to the social, ecological, and economic benefits that they provide for allowing sustainable development.

Waste Pickers

This article presents an approach to compensate waste pickers in the informal sector of Minas Gerais state, Brazil, via a Payment for Urban Environmental Services (PUES) instrument, called ‘Recycling Exchange’. The aim is to evaluate the effects of this instrument on the amount of waste diverted from landfill and reintroduced into the production chain, and to increase recognition of waste pickers’ contributions to the state’s economy. It was found that the ‘Recycling Exchange’ met the fundamental objectives of a PUES: the double social and economic benefits of the social inclusion of waste pickers in the execution of the public policy for solid waste management, and inducing (in the case of glass), ensuring and stabilising (plastic and paper) continuity of the activity of selling recyclables in times of wide price fluctuations for these recyclables. The instrument enhanced the provision of this environmental service and the positive externalities associated with recycling.

Background. Smoking is given by the tobacco consumption. Thus all smoking economic benefits are based on this fact. Some economic sectors are benefited from the smoking economic impact over the health services demand. The magnitude of these economic benefits is given by the relevancy from the effective demand of health services attributable to smoking. Objective. To describe the main economic benefits attributable to smoking. Materials and methods. As theoric methods were used the historic – logic the inductive – deductive and the comparative. As empiric method it used the bibliographic research. Results. The financial resources able to access to the health services may be limited by the same reason that motive the health service demand: the smoking. One of the more singular economic benefits from smoking is given by the smoker earlier death. The smoker over-mortality carries to reduce the demand of Social Security services to retired people agree to life expectation reduction. Much times the unquestionable health valued isn´t sufficiently considered by fiscal authorities who consider more important at short time the practice value from the smoking economic benefits. That’s why it isn´t sufficient with the understanding and acknowledge from the smoking impact over the life quality and life expectation. Conclusion. The social and the human development may not be supported in the existence of a risk factor that reduces the life value reducing the health quality and life expectative at same time, which raise the living cost and favor to a reduced people number across the addiction to the nicotine.

The Impact

Objectives: Starting from the tobacco economy, this paper studies the “surge phenomenon” of macro-economy in developing countries. Methods: This paper studies the impact of tobacco industry on Anhui economy by using the relevant theories of industrial economics, econometrics and regulatory economics, combined with the actual situation of tobacco industry. Based on the analysis of the overall development of tobacco industry, this paper empirically analyzes the relationship between tobacco industry and Anhui economic growth. This paper combs the relevant literature of the existing research results of this theory. Combined with the special fact that government investment accounts for a large proportion in China’s current economic construction, this paper redefines the hypothesis of the investor in the theory of principles. On this basis, the expected equilibrium results of enterprise investment decision-making under government led and market led modes are compared and analyzed by using incomplete information static game model. Results: When the output value of tobacco industry increases by 1%, it will drive the GDP to increase by 0.373%. Secondly, by comparing the economic benefits of tobacco with the social costs of tobacco, it is found that with the economic development, the social costs caused by tobacco increase year by year, but the economic benefits are slightly greater than the social costs. The difference between the two is also increasing year by year. Conclusion: In the context of tobacco control, we should fully consider the advantages and disadvantages of developing the tobacco industry. Under the excessive intervention of the government, the manifestation of the surge phenomenon is more intense, and the final consequence of overcapacity is more serious than that under the market-oriented mode..
