基于因子分析法构建龙泉煤矿4202工作面多级瓦斯预警模型

Construction of Multi-level Gas Warning Model for the 4202 Working Face of Longquan Coal Mine based on Factor Analysis

为了对太原煤炭气化(集团)有限责任公司龙泉煤矿4202工作面瓦斯预警进行研究,连续20d实地测量了4202工作面周边10个测点的瓦斯浓度数据。以此为数据支撑,进行了KMO和Bartlett检验,通过提取主成分等一系列计算得到了工作面多级瓦斯预警模型,为矿井瓦斯预警体系的建立提供一定的帮助,对矿井工作面瓦斯预警具有一定的现实意义。

In order to study gas early warning in the 4202 working face of Longquan Coal Mine, the gas concentration data of 10 measuring positions around the 4202 working face were measured continuously for 20 days. Based on these data, KMO and Bartlett tests were carried out. After a series of calculation, the multi-level gas early warning model of the working face is obtained, which provides some help for the establishment of mine gas early warning system, and has certain practical significance for the gas warning in mine working face.
