最近各矿使用炸药的种类与规格都有了变更,由于我们对于不同质炸药的不同操作方法,没有足够的经验,开始时遇到一些困难,如瓦斯中毒,及爆破效率不高等现象,一部分矿山己经通过对炸药性能了解的研究与试验,克服了这些困难,但有的矿山还在摸索中,这一问题,必须迅速予以解决,因为在一定时期内,局拨炸药的种类与规格还不能完全统一,必须适当的使用现有的炸药,充分发挥其爆破效率,方不致影响年初的生产计划,兹将各种炸药均成分性质及使用注意事项通知如下,希即组织技术人员进行研究试验,并将试验结果与取得的经验及时报局。
Recently, the types and specifications of explosives used in various mines have been changed. Since we do not have sufficient experience in different operational methods for different explosives, we initially encountered difficulties such as gas poisoning and inefficient blasting. Some mines These difficulties have been overcome through research and experimentation on the understanding of the properties of explosives, but some mines are still being explored, and this problem must be solved promptly, since the types and specifications of the explosives that have been set aside for a certain period of time To achieve complete reunification, it is necessary to properly use existing explosives and make full use of their blasting efficiency so as not to affect the production plan at the beginning of the year. We hereby notify the following about the composition and properties of various explosives and the precautions for their use. It is hoped that we will organize technical personnel to conduct research and tests, And the test results and experience gained and the bureau.
