礦井火災一直都是煤礦井下重大災害之一.采空區(qū)自然發(fā)火則是礦井內因火災的主要形式,造成了巨大的資源浪費,人員傷亡和財產損失,因而國家安全生產監(jiān)督管理總局在《煤礦安全生產"十二五"規(guī)劃》中提出了井下火災治理的"超前預防"原則,把"火災成因機理分析,火災預防,監(jiān)測預警"列為急需突破的重點研究領域,特別提到"煤炭自燃引起的內因火災隱患的治理,防止內因火災發(fā)生".因此,完善采空區(qū)自然發(fā)火機理,進一步研究預測預警技術,對科學決策煤礦自燃火災的防治都有著重要的意義

Mine fires have always been one of the major disasters underground in coal mines Spontaneous combustion in goaf is the main form of internal fire in mines, causing huge waste of resources, casualties, and property losses. Therefore, the State Administration of Work Safety proposed the principle of "pre emptive prevention" for underground fire control in the "12th Five Year Plan for Coal Mine Safety Production", and listed "analysis of fire cause mechanism, fire prevention, monitoring and early warning" as a key research area that urgently needs to be broken through, especially mentioning "treatment of internal fire hazards caused by coal spontaneous combustion to prevent internal fire occurrence" Therefore, improving the mechanism of spontaneous combustion in goaf and further researching prediction and warning technologies are of great significance for scientific decision-making on the prevention and control of coal mine spontaneous combustion fires
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. conducted pyrolysis experiments on coal samples to study the spontaneous combustion characteristics of coal seams. The concentrations of gases such as CO, CO2, CH4, C2H4, C2H6, and C3H8 were measured at different pyrolysis temperatures, and the detection temperatures of these gases were determined Based on experimental research and the principle of optimizing indicator gases, the regularity of natural combustion indicator gases changing with temperature was analyzed, and suitable indicator gases for predicting and forecasting coal spontaneous combustion in this mine were selected. This has important guiding significance for improving the accuracy of early prediction and forecasting of coal spontaneous combustion and mine fire prevention
