《煤矿安全规程》(以下简称《规程》)第308条规定:“架线电机车使用的钢轨接缝处,各平行钢轨之间,道岔各部分与道岔心之间,都必须用导线连接。平行钢轨上每隔50m连接一根导线,导线电阻相当于长度相同、断面不小于50mm~2铜线的电阻;钢轨接缝处的电阻不得超过同型钢轨4m长度的电阻值”。我矿架线电机车使用的钢轨共129822m。每8m一个轨端接缝,共有轨端接缝16227个。这些轨端接缝处绝大部分无导线连接,只用鱼尾板连接。由于井下潮湿和行车时震动,鱼尾板的螺丝大部分处于松动锈蚀状态。这样就造成了轨 Article 308 of the Coal Mine Safety Regulations (hereinafter referred to as the “Rules”) stipulates that "wire rails shall be connected between the seams used for overhead locomotives, between parallel rails, and between each part of the switch and the switch center. Parallel to the rail every 50m to connect a wire, wire resistance equivalent to the same length, cross-section is not less than 50mm ~ 2 copper resistance; rail joints shall not exceed the resistance of the same type of rail 4m length resistance. The rails used by mine mine locomotives totaled 129822m. Every 8m a rail end seams, a total of 16,227 rail seams. Most of these rail-end seams no wire connection, only the fish plate connection. Due to wet downhole and driving vibration, most of the fish plate screws in loose rust state. This created a track
