露天煤矿火区爆破高温孔温度测量与分析

Measurement and Analysis of High-temperature Blast-holes in Opencast Coal Mine with Spontaneous Combustion

根据不同工艺环节对高温炮孔温度测量的效率和精度要求以及各种测温仪器测温的不同原理、特点,把接触式测温方法和非接触式测温方法相结合,发挥其性能互补的优势,采用1种或者数种测温方法进行高温炮孔温度的测量,以满足高温爆破作业中有效识别高温炮孔、高温炮孔降温效果评价、起爆器材耐温能力评价和指导高温爆破施工方案制定等方面的要求。

According to the different requirements about efficiency and accuracy when research and mine, the principle and characteristics of the various measurement instruments are compared, and then one or several kinds of methods of temperature measuring, including contact measurement and non-contact measurement method, are used for different aim during high-temperature blasting. The aim of measurement temperature include the effective identification of high-temperature blast-holes, the cooling effect of high-temperature blast-holes, the heat resistant properties of explosives materials and the design guidance for high-temperature blasting.
