摘　　要：为了满足矿井测温试验的需要,对煤矿井下钻孔测温仪器进行了改进,设计研制了一种便携式、多功能、数字化的测温仪器。该仪器不仅精度高,而且还具有成本低、能耗低等显著特点,并在突出危险煤层进行了现场试验,收到了良好的效果,也为课题的继续进行提供了基础。Aimed at matching the experiment needs of measuring temperature in coal mines, in this paper, it was improved. A portable, multifunctional and digital thermoscope was designed and manufactured. Not only it has the characteristic of high precision, but also it has low cost, low energy loss etc. It tested in outburst dangerousness working face. It shows well and supplies foundation for development of subject.
