Practical Study On Gray Theory In Safety Prediction And Safety Assessment Of Non-Coal Mines

With the population growth and rapid development of our national economy, the demand for mineral resources is rapidly growing. After 50 years of efforts, China has become one of the most powerful countries in world in mining exploration, but the non-coal mine production safety situation remains quite grim. Facing such a situation, applying science and technology to improve non-coal mine safety production standards, implementing the guideline that safety is the first and precaution is critical approach to security, studying safety assessment and prediction to enhance our non-coal mine safety standard is necessary and urgent.In this paper, the author studied the existing security assessment methods, development, and the application and promotion situation in our country, based on Grey Theory, the Level Analysis method, to improve Safety Assessment and Safety Prediction of non-coal mines to enhance the credibility of its conclusions.
