目前,黄金矿山井下局扇的控制,一般均采用人工的方法来完成。有些先进的矿山采用了爆破冲击波起动器来起动局扇,但在停止局扇时,仍需要人工进行手工操作。现在我矿已开始推广使用一种局扇气敏电子自动控制器,从而使井下局扇的控制达到了较高的自动化水平。这种自动控制器是我矿的孙福军同志于1987年6月试制成功的,现场的使用情况良好,既实现了井下局扇起动和停止的自动控制,又使井下空气中一氧化碳的浓度达到了国家标准。
At present, the control of underground fans in gold mines generally uses artificial methods to complete. Some advanced mines use a blast shockwave starter to start the bifurcation, but when the baffle stops, manual labor is still required. Now I mine has begun to promote the use of a Bureau of gas-powered electronic automatic controller, so that underground fan control has reached a high level of automation. This automatic controller is my mine, Comrade Sun Fujun successfully trial-produced in June 1987, the site is in good condition, not only to achieve the underground fan start and stop the automatic control, but also so that the concentration of carbon monoxide in the air down to the country standard.
