为更好地防治煤矿安全生产事故的发生,基于煤矿职工“三违”行为是引发煤矿安全事故的一重要原因,通过调查分析了煤矿职工出现“三违”行为的主要原因,并提出了一系列防治煤矿职工“三违”行为的具体对策,以期通过综合应用这些防治对策能进一步规范煤矿职工日常行为,更好的保障煤矿安全生产。 相似文献

钢铁企业的安全生产系统是一个灰色关联系统,采用灰色关联分析法分析钢铁企业生产事故的关键因素。根据2008-2012年全国钢铁企业发生的事故与导致事故发生的各影响因素统计资料分析可知,规章制度不健全,不落实,企业管理不严格,职工劳动纪律松弛;教育培训不够以及违反国家有关法律法规、监督管理不够等是导致事故发生的关键因素,通过对关键因素的控制和管理,可以预防或减少钢铁企业事故的发生。 相似文献

煤矿发生事故,除了环境和设备诱发的原因外,更多的是人为事故。"安全积分"管理以正向激励为导向,变罚款为积分,引导职工自主保安、"我要安全",以对职工最少的罚款获得矿井最大的安全效益,全面提升了企业安全生产管理水平。 相似文献

大量的事故调查显示人的不安全行为是导致煤矿事故发生的主要原因,而安全行为能力的不足则是不安全行为发生的根源因素,对煤矿职工安全行为能力进行分析和研究是预防人因事故,促进安全生产的重要途径.将煤矿企业职工分为决策层、管理层和执行层3个层次,结合人力资源管理中能力的概念,对煤矿职工的安全行为能力进行了定义,并提出煤矿企业人因事故模型;通过分析职工安全行为能力的影响因素,构建了煤矿企业职工安全行为能力评价指标体系,为煤矿企业有效评价人的安全性,预防人因事故提供了一种思路. 相似文献

New, more exact approximated solution to the direct problem of identifying a signal of a vertically oriented magnetic dipole
on a borehole axis is reported. This solution makes possible to process the data of the high-frequency induction logging isoparametric
sounding, including negative values of the measured phase difference. The new approximation enables taking into account the
variable borehole radius that is of special importance when a highly-conductive drilling mud is used. As the obtained expression
is explicit, it can be used for the quick data processing and for solving inverse problems of the borehole geophysics.

1. | A working and a rock mass around it may be defined by one dimensionless parameter λ≥0. This parameter predetermines the behavior of the rock mass with any changes of mine pressure and support resistance. |
2. | With 0≤λ<1 prediction of the behavior is clear: Reaction of the rock mass to any changes in mine pressure and support resistance will have a stable character. |
3. | If λ>1 then stability for the reaction is only retained up to a certain critical condition. Parameters of the critical condition depend on mine pressure, the degree of weakening at contacts between blocks, geometrical dimensions and elasticity moduli. With a changeover through the critical condition there is uncontrolled dynamic release of potential elastic energy for the rock mass. |

Conclusions The deformation of the blocky mass around a working can be interpreted as displacement of the material in a convergent radial
channel with an aperture angle of 360°. A kinematic scheme permitting the formulation of the problem in statically determined
form (similar to the classical scheme for calculation of the pressure of the earth at a supporting wall) is constructed.
Axisymmetric solutions for different levels of block interaction on contact are given. Estimates of the carrying capacity
are obtained in the case of rigid-plastic contact between the block and in conditions of dry friction. It is shown that this
scheme admits of transition in the limit to the accurate solution of the Lame problem in the continuum formulation.
Cases in which increase in the relative slip between the blocks leads to decrease in the interaction force between them (weakening)
are considered. With slight weakening, the deformation is a stable process. If the weakening is greater than a critical level,
the solution becomes unstable, which indicates the uncontrollable release of stored elastic energy from the mass.
