做为瓦斯综合安全措施的一部分,我们在探讨井下发生的灾害形式和变化情况方面,以井下采煤现场为中心,在日常作业条件下,正在进行长时间的定期的观测。在研究井下灾害现象的过程中,我们研制出与目前井下设置的传感器不同的一种新装置,它能够同时监测多种气体,但尚未达到连续测量的程度。在多种气体的连续检测方面,虽然束管技术正在被应用,但是从采气点到分析器之间要达数公里的距离,因而也出现一些问题。
As a part of comprehensive gas safety measures, we are conducting regular long-term observations under daily operating conditions in the context of underground mine occurrences as we explore the types of disasters and changes that occur underground. In the course of studying the underground disaster phenomenon, we developed a new device different from the current downhole sensors, which can monitor multiple gases at the same time, but has not yet reached the level of continuous measurement. In the continuous detection of multiple gases, although beam-tube technology is being applied, a few kilometers from the gas-producing point to the analyzer are required to reach a few kilometers and thus some problems arise.
