The high rotten coal (including the anthracite and meager coal ) radioactive level is relatively low,( 238U: 29.1Bq/kg , 232Th: 25.9Bq/kg , 226Ra: 37.5Bq/kg), obviously lower than the radioactive levels of the brown coal and bituminous coal, and fluctuating range little relatively stable until Lincang uranium germanium colliery HeKai Tian little dragon's pool power plant make , investigate than right far correctly, prove natural radioactive nuclide (238U , 232Th , 226Ra ) than activity transformation in the course of utilizing and give locality radiate influence that environment bring.

高变质煤放射性水平相对较低，（238U：29.1Bq/kg、232Th：25.9Bq/kg、226Ra：37.5Bq/kg），明显低于褐煤和烟煤的放射性水平，且波动范围较小、相对稳定通过对临沧铀锗煤矿田和开远小龙潭电厂作出调查比对，说明了天然放射性核素（238U、232Th、226Ra）比活度在利用过程中的转移以及给当地放射环境带来的影响。

In accordance with the characteristics of coal mining main drainage pump and present state of control and measurement technology,this paper introduces a kind of modularized control and measurement system for coal mining main drainage pump .
