硐室爆破时高温硐室装药的安全防护试验研究

Experimental Research on Safety Protection of Chamber Blasting Charging in High-temperature Chamber

宁夏大峰煤矿硐室爆破时遇到了高温硐室,为了保证硐室装药的安全,对高温硐室内的温度变化进行了监测,并对硐室爆破所用的爆破器材进行了耐高温试验,得出了高温硐室的温度变化规律和爆破器材在高温下的性能变化情况。根据试验研究结果制定了高温硐室装药的安全防护措施,从而保证了高温硐室的装药安全和大爆破的圆满成功。其研究成果具有工程应用价值。

There are some high temperature chambers in Ningxia Dafeng coal chamber blasting. In order to guar-antee the charging safety in chamber, the change of temperature in high temperature chamber was monitored and the performance of explosive materials was tested under high temperature. The rule of temperature change in high temper-ature chambers and the performance change of explosive materials under high temperature were obtained. According to the test results ,the safety protection measures of charging were taken in high chamber, and it successfully guaranteed the charging safely and chamber blasting. The research results have some engineering value.
