Among the 33 deaths, 17 (52%) were certified from a heroin/methadone or opiate overdose, 4 (12%) from drug misuse, 4 (12%) unascertained, and 8 (24%) unrelated to acute toxic effects of drug use.


Second, the unascertained measure was defined and credible identification was set up.


First, the basic knowledge of the unascertained sets was introduced briefly.


Therefore, a mathematical tool, the unascertained measure, was introduced.

 The natural disasters in coal mine involves many unascertained factors which may bring a lot of troubles to the preliminary evaluation of coal mine safety. The index system for preliminary evaluation of coal mine is built on the basis of unascertained mathematical theory and the identification and evaluation criterion for confidence degree and score are given at the same time in this paper. In addition, the unascertained measure model for preliminary evaluation is set up and quantitative analysis... The natural disasters in coal mine involves many unascertained factors which may bring a lot of troubles to the preliminary evaluation of coal mine safety. The index system for preliminary evaluation of coal mine is built on the basis of unascertained mathematical theory and the identification and evaluation criterion for confidence degree and score are given at the same time in this paper. In addition, the unascertained measure model for preliminary evaluation is set up and quantitative analysis of every safety index is made. The comprehensive evaluation on the natural disasters occurred in Huangling No.2 Mine showed that the results of preliminary evaluation accord with the fact, this thus opening up a new way for the preliminary evaluation of coal mine safety.  根据未确知数学理论,建立了预评价指标体系、置信度识别准则及评分准则,构造了矿井安全预评价未确知测度模型,并对矿井的各个安全指标进行定量分析。通过对黄陵二号井的自然灾害状况进行了综合评价,评定结果与实际耦合较好,为煤矿建设项目的安全预评价开辟了一条新途径。  The natural disaster in coal mine involves many unascertained factors. The index system of preliminary evaluation for coal mine is built on the basis of unascertained math theory, and the rules of incredible recognition and score are given at the same time in this paper. In addition, the unascertained measure model is established and quantitative analysis of every safety index is done. It is found by comprehensively evaluating the mine No.2 in Huangling that The result of preliminary evaluation... The natural disaster in coal mine involves many unascertained factors.

In addition, the unascertained measure model is established and quantitative analysis of every safety index is done. It is found by comprehensively evaluating the mine No.2 in Huangling that The result of preliminary evaluation accords with the fact. Thus, a new method is put forward to study preliminary evaluation of coal mine safety.  矿井自然灾害的安全预评价涉及不确定因素众多。本文根据未确知数学理论,建立了预评价指标体系、置信度识别准则及评分准则,构造了矿井安全预评价未确知测度模型,并对矿井的各个安全指标进行了定量分析。用上述方法对黄陵二号井自然灾害的评定结果与实际耦合较好,从而为煤矿建设项目的安全预评价开辟了一条新途径。  After analyzing the shortcoming of the safety assessment method of coal mines,the unascertained measure based on the practice of coalmines is proposed in the paper and the new qualitative and quantitative solution method is introduced to research the safety assessment of coal mines and to overcome the shortcomings.The calculation example shows the efficiency of the method to the safety assessment of coalmines.  在分析了煤炭行业原有安全综合评价缺陷的基础上 ,论文建立了未确知测度模型对煤矿安全进行综合评价。提供了一条定量、定性相结合的煤矿安全综合评价的新途径 ,并用一个实例说明此模型具有一定的实用价值   << 更多相关文摘
