基于一元线性回归的中国煤炭行业年死亡人数与年煤炭产量的预测研究

Prediction Research of Annual Death Numbers and Annual Coal Production in China's Coal Industry Based on Simple Linear Regression

为了预测我国煤炭行业未来安全形势的发展状况,建立了我国煤炭行业年死亡人数与年煤炭产量的一元线性回归预测模型,采用该模型对我国未来3年煤炭行业年死亡人数与年煤炭产量的发展趋势进行了预测。预测结果表明,该模型具有一定的可行性,为预测我国煤炭行业的安全形势提供了可靠的理论依据。

In order to predict development status of future safety situation of China＇ s coal industry ,a prediction model of simplelinear regressionfor annual death numbers and annual coal production in China＇s coal industry was established,and the model was used to predict annual death numbers and annual coal production of China＇s coal industry in three years. The prediction result showed that the model has certain feasibility, which can provide reliable theoretical basis for predicting safety situation of China＇ s coal industry.
