The interaction between workload and job satisfaction was significant (t = − 3.460, p = 0.001 < 0.05). It means that when the workload has an impact on miners’ Employees of 27 coal mining enterprises in Shandong, Henan, Hunan and other places in China were surveyed and sampled by stratified random sampling, and 1514 valid questionnaires were obtained.Relevance Proof of Safety Culture in Coal Mine

Coal mine safety production is one of the most urgent problems in China. Monitoring and control of underground gas and coal dust is vital to providing a safe The seam mining ratio is proposed for the mining of close-spaced coal seams, and its meaning is the ratio of the thickness of the interlayer rock layer to the mining height of the lower coal seam, η; that Control of the Internal and External Staggered

3.1.2 Construction of intelligent coal mine knowledge map. Through the establishment of information entities, the mapping from the physical space to the digital space is realized. This mapping includes not only physical entities (e.g., coal mining machines, hydraulic supports, and tunneling machines), but also time entities (e.g., roof The rate of coal mine accidents in China has of the unsafe behavior of coal miners are established. The internal and external dynamics of groups are analyzed and the importance of each factor is calculated and determined. On this basis, suggested correction measures are put forward. Then, in combination with a questionnaire, the Group dynamics analysis and the correction of coal miners' unsafe

Abstract and Figures. Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective andMaslow’s hierarchy-of-needs theory has been used to predict development of Quality of Life (QOL) in countries over time. In this paper an attempt has been taken to derive a methodological validation of quality of life questionnaire which have been prepared for the study area. The objective of the study is to standardize a questionnaire tool to Methodological Validation of Quality of Life Questionnaire for Coal

Coordinated and sustainable development of production-living-ecological space (PLES) is directly related to the global energy security and quality of life in coal areas. However, the current surface subsidence control methods have some problems, such as low resource recovery rate, high cost, insufficient materials, which are difficult to meet the Innovation plays a critical role in the mining industry as a tool to improve the efficiency of its processes, to reduce costs, but also to meet the increasing social and environmental concerns among communities and authorities. Technological progress has also been crucial to allow the exploitation of new deposits in more complex scenarios: Innovation in the Mining Industry: Technological Trends and

Based on questionnaire survey results and analytic hierarchy process (AHP), assessment judgment matrixes are constructed, effect weight is calculated, and consistency check is conducted. The1. Introduction. As an important basic energy source and industrial material, coal has made a prominent contribution to China's economic development (Wang et al., 2018).However, various safety-related accidents occur frequently in coal mines (Cheng et al., 2017; Hu et al., 2018), which not only have a negative impact on economic Human factors analysis of major coal mine accidents in China based
