# Cause Analysis of Coal Mine Gas Accidents in China Based on Association Rules
## 2 Methods
### Countermeasures and Suggestions  
According to the coal mine gas accident cause chains combined with the actual coal mine gas accident case, the following countermeasures and suggestions are put forward:  
Strictly perform the duties of coal mine safety supervision and strengthen the inspection and guidance of coal mine production enterprises in the area under their jurisdiction. For example, on 10 May 2017, a serious gas combustion accident occurred in the Yandefang Coal Mine in Shanziwei, Longyan City, Fujian Province. The expiration date of the safety production license of this coal mine was 2016, so the mine was suspended from 2016. The absence of safety protection measures and the illegal organization of the workers into mining operations resulted in the accident. When the coal mine gas accident causes chain 1, poor supervision by the safety supervision bureau and illegal production by coal mining enterprises are the essential causes of accidents. As a result of this, the safety supervision bureau should take responsibility and strengthen safety management. At the same time, the safety supervision should strictly investigate and punish illegal mining behavior and cross-border mining behavior of coal mine production enterprises operating without a production license, and ask the coal mine

Figure 9: Coal mine gas accident causes chain 2 (The numbers on the arrows indicate the degree to which the two are related). to stop production and rectify their enterprise within a time limit, so as to eliminate hidden safety risks in the embryonic stage. The management of coal mine production enterprises should strictly abide by the relevant laws and regulations of the state, set up correct values, put safety in production first, and should not blindly pursue output and interests at the expense of safety protection. Earnestly implement the main responsibility of enterprise safety production and strengthen safety education. For example, there was a gas explosion in the Goutou Coal Mine in the Yunnan province on 22 September 2019, a gas explosion in the Kongjiagou Coal Mine in the Guizhou Province on 13 December 2017, and a large coal and gas outburst accident in the Zhushanchong Coal Mine in the Hunan Province on 8 December 2017. In view of such situations, coal mining enterprises should earnestly implement the provisions of the \"Regulations on Reporting and Investigation of Production Safety Accidents\" and report coal mine accidents truthfully and in a timely manner. Illegal supervision will lead to a lack of good management culture in the daily operation of coal mine production enterprises. First of all, good management culture must: have a perfect safety management organization; be equipped with enough professionals; not have personnel without a certificate or a certificate that does not match the job; not illegally hire personnel; formulate practical emergency rescue plans for accidents, and conduct regular emergency training for personnel; ensure adequate investment in production safety, material, and financial security; and strictly follow incident reporting procedures when accidents occur. In addition, coal enterprises need to, on the one hand: strengthen safety education and training of personnel, to pay attention to workers' safety and in turn pay special attention to the worker's coal mine gas accident prevention education. On the other hand, lectures, competitions, and other forms of training should be held regularly to popularize and assess the theoretical knowledge of coal mine gas accidents, and safety publicity and education should be carried out in the form of radio, television, and short videos, so that employees can consciously abide by safety rules and regulations and carry out production operations in strict accordance with the operation rules. Ensure that the relevant measures of operation are put in place to improve the gas control level.
