重新开发不同地质和开采条件以及开采深度往往比近10年要深的地下煤炭,就需得对安全炸药的研制技术做进一步提高。按不同条件正确选用炸药种类之前提就是很好论证安全炸药的分类,因而也是头等重要的安全问题。一、使用安全炸药的危险情况和条件该分类可表现为如下两种形式
Redevelopment of underground coal of different geological and mining conditions and exploitation of deeper underground coal than it has been for more than a decade necessitated the further improvement of the technology for the development of safe explosives. Proper selection of explosives according to different conditions before the premise is to demonstrate the classification of safety explosives, and therefore the first and foremost an important safety issue. First, the use of safe explosives hazardous conditions and conditions The classification can be expressed as the following two forms
