This paper describes the rationale of catastrophe theory, designs the index system of coal mine safety management and establishes the evaluation model of mine safety management based on catastrophe theory. We can see that the level of mine safety management of Pingdingshan Coal Group by applying the evaluation model of mine safety management based on catastrophe theory. The model can objectively and...
The working face of high mining have long length of mining and strike, so the area of goaf is large, often cause air return and local gas (especially the top corner) overrun, lead to the gas of working face overrun frequently and forced to shut down, even bring on significant pernicious accidents, cause casualties and great economic losses. This paper use the method of field testing and theoretical...
Through analysis on domestic flat pitch seam Cross-cut exposing prominent anti-Outburst Coal technology, in connection with Cross-cut coal and Gas outburst law, take flowing deformation assumption as theology mechanism principle, study up on the effect of coal seam crosscut obligate rock pillar's resistance to the prominent, the way of Gas drainage, the form of coal seam Cross-cut pilot tunnels' and...
The improved grey correlative model was put forward in order to improve the objectivity of grey synthetic evaluation method. Balanced degree was ascertained by entropy theory. Weighted grey correlative degree was synthesized by grey correlative coefficient and entropy weights. Balanced adjacent degree, which was derived from weighted grey correlative degree and balanced degree, was taken as the evaluation...
A friction hoist sliding protection system(FHSPS) which taking use of Siemens S7-300 and WinCC configuration software is designed in this paper. According to the probation in a coal mine of Qidong, China, any mistaken action is find since putting into use, it not only can alarm the sliding malfunction, but also can brake the wirerope and cage while the malfunction comes up.
Safety is an element of extreme priority in mining operations, currently many traditional mining countries are investing in the implementation of wireless sensors capable of reducing the number of accidents; through early warning signs to prevent injuries, dead and significant economic losses. The application of sensors capable of measuring in real time variables of interest, promises to be of great...
Minerals are the primary resources of economic and social development. But the nature of mining and mineral development is such that various adverse impacts upon the local communities are usually inevitable. Consequently, the process of mining-led economic and social development is often associated with tensions among corporate mining objectives, recipient community needs, and governmental policy...
Under the guide of green mining theory of coal resource and green logistics concept, green logistics is introduced into the green mining technology. Firstly this paper defines the concept and connotation of green mining logistics based on analysis of green mining technology and green logistics. Then gives the composition of green mining logistics according to coal flow and material flow underground...
According to the statistics, roof and side fall accidents often occur and jeopardize greatly in coal mines. The variation of the strain and stress in the surrounding rocks of the mine roadway can predict the accident. How to obtain the strain and stress is the key point of the prediction. This paper provides a method on the case. Firstly the principle of monitoring stress in surrounding rocks of mine...
Through the theoretically analyzing of the foundation of outburst prediction indexes and the existing prediction data of coal mine, a mathematics model was established with the dimension theories by considering with weights of dominant factors for ascertaining sensitive factors of coal seam. The established model and grey relevancy analysis were successfully verified in four coal mine of Pingdingshan...
As a modern security design, Inherent Safety means that equipment and facilities is able to contain the inherent fundamental features to prevent accidents. Mine hoist is the most important equipment in the coal production. How to achieve safe, reliable, efficient production, has been the focus study at home and abroad. Inherent safety is reflected in hoist design, primarily through the design measures...
This article starts from the current background of coal mine safety situation and combines with the status of coal mine safety research and computer network technology development, it gives the design of physical structure and logical structure of multimedia alarm system for coal mine safety and discusses and researches its implemental key technologies.
In this paper, we propose a new multi-expert decision-making method based on induced OWA operators for coal mine safety evaluation. Aggregation operators are crucial to decision-makers when they make decisions. The Ordered Weighted Aggregation (OWA) is the most common operator to aggregate the arguments that are the exact numerical values. However, the decision-makers may have vague knowledge about...
In this paper, in accordance with the composition and features of ventilation safety monitoring information fusion system in the coal mine, analyzes the necessity for multi-sensors management. Underground for complex structure, wide area of the monitoring, usually the monitoring process is divided into many small targets monitoring area, the monitoring area of the mine ventilation system security...
Accident is originated by hidden danger. Discovering and removing hidden dangers is one main approach to prevent and control accidents. This paper collected and analyzed the information of hidden dangers from multiple coal mines. On that basis, we put forward concepts of hidden danger information and standard database of hidden danger information, introduced the structure and build flow chart of standard...
A new type of monorail hanging technology was invented to solve the auxiliary transportation problem in soft rock or coal bed roadway, and clearly introduced the hanging scheme and making a feasibility analysis. This new type of monorail hanging technology makes the monorail application in soft rock or coal bed roadway to be possible, solves a major problem in mine auxiliary transportation mechanization...
The sense of mining progress was analyzed. The model of production function considering mining technical progress and mining condition of coal bed was proposed. The growth equation and the production function were deduced when the two factors were considered. The research indicates that mining technical progress has a great effect on the output of mine enterprise when mining technology develops promptly...
RFID is a non-contact automatic identification technology that uses radio frequency signals automatic recognizes target and access to relevant data. The identification work does not require human interference and can work in variety of harsh environments. But if there is no network to transmit data, it will be difficult to play its advantage. Under the influence of environmental conditions, the traditional...
In the process of coal mine construction, it is significant that how to identify the risk factors and to take measures to prevent the occurrence of safety accidents for the mine investment unit to speed up the construction of the new mines and exploit the coal energy rationally. With the ability of structural equation model that processes the variables and their relationship, this article applied...
