一、概 述电子设备具有体积小、重量轻、寿命长、无机械磨损、控制方便、维修简单、易于实现自动化等优点。电子技术已经渗透到国民经济和人民生活的各个领域。但国内电子技术在坑探方面的应用仍是十分有限的。从七二年开始，我们将电子技术逐渐应用于坑探工程设备的改造中，取得了较好的效果。几年来，完成了硅整流启动器、鼓风机断相保护装置、装岩机无触点开关、无线电遥控道岔、水泵自动控制装置、可控硅充电机、可控硅脉冲调速电瓶车、鼓风机烟雾自控器等八项技术革新。虽然这些项目比起先进的电子 I. Overview Electronic devices have the advantages of small size, light weight, long life, no mechanical wear, easy control, simple maintenance, and easy automation. Electronic technology has penetrated into all areas of the national economy and people’s lives. However, the application of domestic electronic technology in pit exploration is still very limited. Since 1972, we have gradually applied electronic technology to the renovation of pit engineering equipment and achieved good results. Over the past few years, silicon rectifier starters, blower phase failure protection devices, rock loader contactless switches, radio remote control switches, water pump automatic control devices, thyristor chargers, thyristor controlled pulse speed battery car, and blower smoke control have been completed. Eight technological innovations. Although these projects are more advanced than advanced electronics
