基于物理降温静态爆破防喷孔实验研究
|
摘要
为了解决静态爆破水化过程中因周围介质散热太慢导致的喷孔问题,基于物理降温原理,利用水比热容大、吸热能力强和钢质材料导热性能好的特点,吸收水化产生大量的热,研制一种静态爆破防喷孔装置,对静态爆破过程中破碎剂的温度和膨胀力进行测试。研究表明:未加防喷孔装置,破碎剂反应迅速,破碎剂的温度和膨胀力剧增,能量集聚,容易发生喷孔;加防喷孔装置,破碎剂水合温度增加缓慢,膨胀力增加稳定,且不影响最终膨胀力值,达到防喷孔的目的。
To solve the problem of spraying hole caused by the too slow heat dissipation of the surrounding medium in the static blasting hydration process,based on the principle of physical cooling,a large amount of heat produced by the hydration was absorbed by using the characteristics of large specific heat capacity and strong heat absorption capacity of water and good thermal conductivity of steel materials. A static blasting anti-spraying hole device was developed,and the temperature and expansion force of the cracking agent in the static blasting process were tested. The results showed that without the anti-spraying hole device,the cracking agent reacted rapidly,the temperature and expansion force of the cracking agent increased sharply,and the energy gathered,so the spraying hole was easy to occur. When adding the anti-spraying hole device,the hydration temperature of the cracking agent increased slowly,the expansion force increased steadily and would not influence the final value of expansion force,so as to achieve the purpose of preventing the spraying hole.
