Mining monitoring equipment and goaf gas monitoring method

The invention discloses mining monitoring equipment and a goaf gas monitoring method. The mining monitoring equipment comprises a gas chromatograph, an underground gas transmission mechanism and a gas path switching mechanism. According to the mining monitoring equipment and the goaf gas monitoring method, gas in the goaf can be monitored on site, automatic gas path switching can be achieved through the gas path switching mechanism so that the gas chromatograph can analyze the gas in each monitoring point, by arranging a pressure difference measuring instrument, the pressure difference or energy level of the two monitoring points can be monitored, the operation is convenient, and accurate monitoring results can be provided for goaf air leakage and residual coal spontaneous combustion research. 本发明公开了一种矿用监测设备及采空区气体监测方法，包括气相色谱仪、井下气体传输机构和气路切换机构。本发明公开的一种矿用监测设备及采空区气体监测方法，可以对采空区中的气体进行实地监测，通过气路切换机构可以实现自动切换气路，以供气相色谱仪对每个监测点中的气体进行分析，通过布置压差测量仪，可以对两个监测点的压差或能位进行监测，操作方便，可以为采空区漏风与遗煤自燃研究提供较为准确的监测结果。
