瓦斯浓度异常预警系统及应用

Gas Concentration Abnormality Forewarning System and its Application

随着矿井开拓延深,瓦斯变化呈多样性。当井下瓦斯浓度变化异常且低于监控报警值时不易引起注意,而这种忽大忽小的变化很有可能是大的隐患前兆。该系统实时采集到井下瓦斯值,对瓦斯浓度的变化进行比较分析,当出现异常情况时发出报警,提醒相关人员注意。对瓦斯浓度异常,起到了早预防、早知道、早控制的作用。

With the mining developing, the change of gas will be diversity. Now it can not be reminded when the gas concentration is lower than alarm value and changes unusually, but it may be a hidden dangerous pre- monition. The system collects realtimely the gas value, the change of the gas concentration. A forewarning information will remind to pay attention to it. It plays a role for prevention and control of gas concentration abnormality.
