1. Product Features
FD-50-200D mining exploder is a power switching devices, which is used to detonate electric detonators, with advantage of low waste, high power, can be worked under those mine well which is in danger of methane, gas, etc.
Product Performance Standards: GB/T7958-2000, Q/RD003-2008.
2. Environment and Conditions
a) Environment temperature: 0℃~+40℃
b) Under coal well, contain explosive gas(methane).
C) Air relative humidity(RH): < 95%(25℃)
d) Atmospheric pressure: 80~ 106kpa
e) Storage environment temperature: 40℃~+60℃
