“…Consequent is the production of noisy and unhealthy work environment (Dube et al , 2011), although the impact is limited to the workplace only (Ahmad et al , 2014, Government-of-India, 2000). As a result, mining workers suffer from various mental and physical disorders, such as noise-induced hearing loss, high blood pressure and headaches (HasanuzzamanBhar, 2016; Kamaruzzaman et al , 2021).…”

PurposeEnvironmental pollution and corresponding adverse health impacts have now become a significant concern for the entire planet. In this regard, analysts and experts are continually formulating policies to reduce environmental pollution and improve natural ecological conditions. To aid in coping with the ecological predicament, a framework has been developed in the present study to inspect the adverse environmental impacts and related health issues of coal mining.Design/methodology/approachThe parameters for this study have been identified through a review of the literature and finalized 23 critical parameters of air, water, land and soil, and noise related to coal mining by consultation with experts from industry and academia. Finally, the parameters have been categorized in accordance with the level of threat they pose to the environment by assigning weight using the Bradley–Terry model considering attitudinal data acquired by a questionnaire survey.FindingsIt is found that coal mining has a relatively higher impact on four attributes of “air pollution” (suspended particulate matter [SPM], respiratory particulate matter [RPM], sulfur dioxide [SO2] and oxides of nitrogen [NOx]), followed by “land and soil pollution” (deforestation and surface structure diversion), “noise pollution” (vehicle movement) and “water pollution” (water hardness, total solids (TSS/TDS) and iron content). It is also found that raising the air concentration of SPM and RPM results in increased respiratory and cardiopulmonary mortality. Therefore, reducing dust concentrations into the air generated during coal mining is recommended to reduce air pollution caused by coal mining, which will reduce contamination of water and land and soil.Research limitations/implicationsThe model built in this study is a hypothesized model that relied on the experts' opinions considering the parameters of coal production only. However, the parameters related to the usage of coal and its consequences have been excluded. Further, only industrial and academic experts were considered for this study; however, they excluded local people, coal mining personnel, policy authorities, etc. Therefore, the study findings might differ in real circumstances. The research can further be reproduced by considering the parameters related to the use of coal and its consequences, considering the opinions of the local people, coal mining personnel and policy authorities.Practical implicationsCategorizing the parameters according to the threat they pose to the environment due to coal mining can help the decision-maker develop an effective policy to reduce environmental pollution due to coal mining by considering the parameters on a priority basis. In addition, the results further help the decision-makers to assess the environmental impact of coal mining and take necessary action.Originality/valueThe study has developed a framework using the Bradley–Terry model to categorize the environmental parameters of coal mining to develop effective environmental policies, which are original and unique in nature.

Advancement in engineering provides various improvement in quality life while taking consideration of important factors for safety and environment. The use of mower food maintenance of land it is very common across several parts of the world with some frequent noise generated through its operation. This article is an attempt to study the noise and frequency generated through the vibrations of mower blade. In this study, an integrated design for designing, testing and developing mower blade that generates less noise is presented. For designing efficient blade that produces less noise, we have implemented various engineering approaches such as rapid product design, process of re-engineering and reverse engineering. The simulation of the designed blade is carried out through CAD software where the design prototype is analysed for its performance. The outcomes of the prototype are tested through simulation and its performance is compared for the determination of success of proposed design at different variations in frequency level. It is observed through the experimentation that the noise and vibration differences are generated through load carrying vehicles, mowers with riding capacity and simple mowers. From the analysis, mower with riding capacity is observed as safest among all other types of machines.
