Description
技术领域technical field
本实用新型涉及涉及煤矿瓦斯灾害预警与治理领域，具体地说涉及一种煤矿通风与瓦斯含量实时监测系统，用于煤矿瓦斯含量的监测和排放。The utility model relates to the field of early warning and control of coal mine gas disasters, in particular to a real-time monitoring system for coal mine ventilation and gas content, which is used for monitoring and discharging of coal mine gas content.
背景技术Background technique
众所周知，瓦斯一直都是井下作业的头号大敌。瓦斯是古代植物在堆积成煤的初期，纤维素和有机质经厌氧菌的作用分解而成。在高温、高压的环境中，在成煤的同时，由于物理和化学作用，继续生成瓦斯。瓦斯是无色、无味、无臭的气体，但有时可以闻到类似苹果的香味，这是由于芳香族的碳氢气体同瓦斯同时涌出的缘故。瓦斯对空气的相对密度是0.554，在标准状态下瓦斯的密度为0.716kg，瓦斯的渗透能力是空气的1.6倍，难溶于水，不助燃也不能维持呼吸，达到一定浓度时，能使人因缺氧而窒息，并能发生燃烧或爆炸。瓦斯在煤体或围岩中是以游离状态和吸着状态存在的。As we all know, gas has always been the number one enemy of underground operations. Gas is formed by the decomposition of cellulose and organic matter by anaerobic bacteria in the initial stage of coal accumulation by ancient plants. In the environment of high temperature and high pressure, while coal is formed, gas continues to be generated due to physical and chemical effects. Gas is a colorless, tasteless, and odorless gas, but sometimes you can smell an apple-like aroma, which is due to the simultaneous release of aromatic hydrocarbon gas and gas. The relative density of gas to air is 0.554. Under standard conditions, the density of gas is 0.716kg. The permeability of gas is 1.6 times that of air. Suffocate due to lack of oxygen and can burn or explode. Gas exists in free state and sorption state in coal body or surrounding rock.
当其在空气中的浓度超过55％时，能使人很快窒息死亡，是煤矿生产中的主要危害因素。防止瓦斯集聚的基本方法是以足够的风量将瓦斯冲淡，排出地面。当瓦斯涌出量很大时，还须用专门措施控制瓦斯的涌出，最有效而广泛使用的方法是用管道将瓦斯抽到地面。When its concentration in the air exceeds 55%, it can cause people to suffocate and die quickly, and it is the main hazard factor in coal mine production. The basic method to prevent gas accumulation is to dilute the gas with sufficient air volume and discharge it to the ground. When the amount of gas gushing is large, special measures must be taken to control the gushing of gas. The most effective and widely used method is to pump the gas to the ground with pipelines.
随着现代技术的迅速发展，煤矿瓦斯灾害的治理发生了革命性变化。有效治理瓦斯灾害，就必须对瓦斯含量做出准确可靠的监测，在瓦斯含量高出危险值时进入抽风排放。但现有的煤矿瓦斯检测系统中，瓦斯含量的监测主要是通过便携设备(如瓦斯检测仪等)来完成的，这使得瓦斯含量数据存在间歇，不能及时反馈到地面。也无法进行及时有效的抽风排放。With the rapid development of modern technology, the management of coal mine gas disasters has undergone revolutionary changes. To effectively control gas disasters, it is necessary to make accurate and reliable monitoring of the gas content, and enter into the ventilation when the gas content is higher than the dangerous value. However, in the existing coal mine gas detection system, the monitoring of gas content is mainly done through portable equipment (such as gas detectors, etc.), which makes the data of gas content intermittent and cannot be fed back to the ground in time. Also can't carry out timely and effective ventilation discharge.
