抚顺矿务局老虎台矿矿井水砂充填系统的电话通讯,长期以来一直采用地面砂井电话室会议分机接井下便携式磁石电话的方式,由于这种电话为非防爆型,根据《煤矿安全规程》规定,它不适合在沼气矿井使用。但长期以来,国内一直没有适合该矿条件的防爆产品,不得不继续使用非防爆型的磁石电话,使矿井的安全生产受到威胁。因此,该矿研制成功了CDO—1型充填电话耦合器,并于1988年7月通过了局级技术鉴定,专家的评议结论是:该耦合器具有国内先进水平,定为局先进科研成果并在全局推广使用。这种充填电话耦合器主要用于煤矿充填作业的通讯系统,接于井下便携式话机(送受话器)与地面注砂井电话室 HYF3型会议分机之间。该耦合器为一般兼矿用本质安全型,与之相连接配合使用的送受话器为本质安全型。该耦合器经煤炭科学研究总院抚顺分院电气防爆检验站检验合格。
Fushun Mining Bureau of Tiger Station ore mine water sand filling system for telephone communications, has long been using the ground floor sand well telephone conference room extension portable magneto phone way, because this phone is non-explosion-proof, according to “Coal Mine Safety Regulations” It is not suitable for use in biogas mines. However, for a long period of time, there has been no explosion-proof product suitable for this mine in China, and the non-explosion-proof magnet telephone has to be used continuously to threaten the mine safety. Therefore, the mine developed a successful CDO-1 type filling phone coupler, and in July 1988 passed the bureau-level technical appraisal, the expert’s conclusion is that the coupler has the advanced domestic level, as Bureau of advanced scientific research and In the global promotion and use. This type of telephone coupler is mainly used in the communication system of coal filling operation, between the underground portable telephone (receiver) and the ground payphone booth HYF3 conference extension. The coupler is also used in mine and intrinsically safe type, connected with the use of the receiver is intrinsically safe. The coupler by the Coal Research Institute Fushun Branch Electrical Explosion-proof station inspection pass.
