Abstract

International construction safety is still a grim backdrop, China Coal Construction into the construction of a new round of high tide, which mine construction project safety accident-prone. Mine construction project safety management is an important part of the coal mine safety management, but a long time has not been given due attention. Mine construction project safety management is different from the production of coal mine safety management is different from the ground for general industrial and civil construction projects. Mine construction project is a large-scale integrated projects, the main part of the project is under complex geological conditions, soft rock layers, water-rich, containing gas complex occurrence conditions; compared with the production of the mine for the first time opened a seam strata the outstanding coal and rock with water damage, and other gas outburst higher risk; construction space is small compared with the ground construction, heavy construction equipment, poor operative field, more complex operating environment; mine construction project operating groups by educational attainment low, lower the proficiency of workers, higher intensity work, construction involves blasting operations, mine construction project participants and management body more, the stability of the project organization, security management more difficult, resulting in safety management mode production of the mine there is a big difference, the greater the degree of risk, so the need to focus on mine construction project safety incidents mechanism and control measures. The paper argues that the mine construction project safety system is a complex socio-technical systems, with complex characteristics: security system is particularly complex, interdependent multiple subsystems, nonlinear, highly dynamic, open and interaction security system involving multiple feedback process, including hard and soft data, and security policies and security measures have resisted. Draw on the traditional cask theories security entropy concept exploration to establish security cask model, the paper presents the point of view of the construction project of the construction of intrinsically safe mine. Using Interpretative Structural Modeling (ISM) method to parse the mine construction project safety system structure, the security system of the mine construction project is divided into field operations layer, security layer, four structural levels of decision-making management and supervision norms layer to define the mechanism of security incidents in actors. Improved analytic hierarchy process to construct a gas to enhance the transport, flooding, roof, transportation, falling from height, the templates collapsed and poisoning, suffocation 8 safety incidents caused due to the hierarchical structure model to analyze the mechanism of its safety incidents cause given The corresponding accident causation mechanism Figure and security cask model and security systems conclusions of the structural level analysis of the mechanism and the effects of accident causation. System dynamics to build the class mine construction project safety incidents mutation mechanism model, reveal the mechanism of security incidents: mine construction project safety incidents project safety barrels short board environmental management short board, the equipment short board and staff results of the short plate coupling, the coupling effects of unsafe behavior generated by the four structural layer of security systems is a project safety decreased gas occurs when the project safety below the threshold enhance wellbore, flooding, roof, transportation , falls, templates collapsed and poisoning and asphyxia security of accident. Unsafe behavior coupling theory proposed mine construction projects on the basis of safety incidents mechanism: safety incidents is the safety systems on-site job layer, the four structural level security layer, decision management and supervision norms layer unsafe behavior coupled a result, the rich safety accident causation theory. Build a mine construction project unsafe behavior impact on project safety mechanism of structural equation model, questionnaire data analysis, found that the four mediating variables of unsafe behavior \four exogenous latent variables on the safety of the project three mediating variables \project safety mechanism. SOM neural networks to achieve a highly nonlinear mapping between mine construction project the characteristics of security incidents and accidents Category mapping results confirm that the workers in unsafe behavior factors, equipment factors, environmental factors and management factors coupled will lead to a corresponding security accidents, can take advantage of the mechanism of safety accident prediction. The proposed integrated security control point of view, given the unsafe behavior of mine construction project structures and systems of control and management information systems to develop key technologies recommended, in order to strengthen the control of the mine construction project safety incidents. The paper Figure 67, Table 91, and 225 references.
