针对新河矿5301工作面顶板深孔预裂爆破盲炮,结合现场调查提出假设:现场操作人员错误的使用静态破碎剂填塞炮孔,静态破碎剂反应将炮孔内的矿用电话线或者雷管脚线损坏造成断路或短路,从而导致了本次事故。通过三组实验探究静态破碎剂对钢管内导线的影响,根据实验结果验证提出的假设,进行分析研究。
In view of the deep-hole pre-splitting blasting of the deep-hole prefabricated blind roof of Xinhe Coal Mine 5301, this paper presents the hypothesis on the basis of on-the-spot investigation that the site operator mistakenly uses the static breaker to fill the blasthole. The static crusher reaction changes the mine telephone line or mine Pinch line damage caused by open circuit or short circuit, resulting in the accident. Three groups of experiments were conducted to investigate the influence of static crushing agent on the conductor in the steel pipe. The assumptions made were verified according to the experimental results and analyzed.
