摘要:
煤矿在生产过程中，采空区遗煤自燃会给矿井的生命与财产安全带来巨大威胁。将矿井采空区氧化升温带看作一个系统，系统呈现的高浓度CO由氧化升温带的遗煤、空气、蓄热条件等各类因素共同影响产生。通过对复杂系统表现出的涌现性规模效应、结构效应、高层次有而低层次没有的三方面特性进行分析，得出采空区氧化升温带高浓度CO产生规律及下属关联因素。在此基础上根据涌现性理论指导，针对神东补连塔煤矿22410采空区氧化升温带高浓度CO治理问题，结合工作面生产现场地质构造、上覆煤柱、采煤工艺、机电故障等实际条件，从煤体易自燃特性、采空区超量遗煤、发达的供氧通道、综采工作面迟缓的推进速度4个方面深层次分析了采空区氧化升温带高浓度CO产生原因，针对性地实施了控制遗煤、封堵漏风通道、上隅角向采空区灌浆、上隅角堆建岩粉墙、工作面风量控制、上隅角及采空区气体“三位一体”实时监测等多项综合治理措施后，采空区氧化升温带高浓度CO问题很快得到了有效控制，从而避免了综采工作面在回采过程中采空区发生自然发火的危险，避免了巨大的经济损失，同时确保了人员的生命安全。由此得出结论：系统涌现性特点可以指导解决煤矿在生产过程中遇到的潜在灾害问题。
Abstract:In the production process of coal mines, the spontaneous combustion of residual coal in gob will bring great threat to the safety of mine life and 〖JP2〗property. In this paper, the oxidative heating zone of mine gob was regarded as a system. The high concentration of CO presented by the system was affected by various factors such as residual coal, air and heat storage conditions in the oxidative heating zone. By analyzing the emergent scale effect, structural effect, and low-level characteristics of the complex system, the production law of high-concentration CO in the oxidation heating zone of gob and the subordinate correlation factors were obtained. On this basis, according to the theoretical guidance of emergence, in view of the problem of high concentration CO control in the oxidative heating zone of 22410 gob in Bulianta Coal Mine of Shendong, combined with the actual conditions of the geological structure of the working face, the overlying coal pillars, the coal mining technology and the mechanical and electrical failures, the causes of high concentration CO in the oxidation heating zone of the gob were deeply analyzed from four aspects：the spontaneous combustion characteristics of the coal body, the excess residual coal in the gob, the developed oxygen supply channel and the slow advance speed of the fully mechanized mining face. After the comprehensive control measures such as controlling the residual coal, blocking the air leakage channel, grouting from the upper corner to the gob, piling the rock powder wall in the upper corner, controlling of the air volume of the working face, and real-time monitoring of the upper corner and the gob gas, the high concentration CO problem in the oxidation heating zone of the goab was quickly and effectively controlled, thereby avoiding the risk of spontaneous combustion in the gob of the fully mechanized mining face in the mining process, and avoiding the huge economic losses. At the same time, the safety of personnel is ensured. From this, it is concluded that the emergent characteristics of the system can guide and solve the potential disaster problems encountered〖JP〗 in the production process of coal mines and have great application value.
