Can you pour Dexpan mix into a hole?
Otherwise, if you pour the Dexpan mix into holes that are too warm, it could cause the compound to dry too quickly and cause a blowout. The other advantage to drilling your holes before buying the compound is that you can measure the depth of your holes to determine exactly how much mix you need.

I recommend blowing some air into them using an air compressor if you have one. You can also use a shop vac. I would NOT recommend spraying water into the holes. I did this and I had trouble getting all the water out which can cause issues with your mixing.
What explosives are used in rock blasting?
What explosives are used in rock blasting? – Collectively, explosives used to break rocks are known as fracture explosives which distinguishes them from accessories such as detonators and others used to initiate a blast in a controlled manner. They are detonable substances or devices that produce a high-intensity shock wave and large volumes of gas which, being confined in a hole, expand rapidly, entering existing minor cracks in the rock, and creating new cracks to break the rock. Mining is the largest consumer of civil explosives including other rock blasting applications such as quarrying and tunnelling. Gunpowder also known as black powder was the first generation of explosives used in all applications. About 1000 years ago, the Chinese invented these explosives, with the first European sources manufactured by the Germans in the early 1300s. Let us broaden our scope to detonators, these are devices used to trigger these explosives in rock blasting. Detonators can be chemically, mechanically, or electrically initiated. Different explosives require different amounts of energy to detonate. Detonation is a necessity for the explosive to get triggered for rock blasting. Explosives are an essential part in the overall fragmentation system of a mine cycle and blasting technology has become an art involving use of calculated number of explosives to yield a predetermined volume of rock material broken down into pieces. This article focuses on types of explosives used, chemistry of explosives, technical aspects of blasting and selection of explosives used in rock blasting.
What is the most commonly used explosive in mining?
The most commonly used explosive in mining globally is ammonium nitrate fuel oil (ANFO ). It was introduced for blasting operations in the 1950s. Chemically, ANFO is ammonium nitrate mixed with fuel and proper mixing of AN and FO is important for predictable explosive performance.
How to initiate a blast?
In many cases, a detonator is insufficient to ensure effective detonation of explosives in a blasthole. A primer, which is a cartridge of high energy explosive into which a detonator is inserted , is used to initiate the detonation of a column of explosives in a blasthole. Boosters may be used, with one or more additional high-energy cartridges placed at intervals along a hole to increase VOD. Containment of energy of explosives in a blasthole is achieved through tamping or stemming which is a plug of inert material such as sand or mud, placed near the mouth of the blasthole. Decking is then the practice of placing plugs of inert material at intervals along a hole to limit energy concentration.
What are the different types of explosives?
Explosives are classified into low and high explosives. Low explosives were the earliest to be developed. These lead to an explosion which is really a rapid form of combustion in which the particles burn at their surfaces and expose more and more of the bulk until all is consumed. An example is black powder which is commonly known as gunpowder. It is mixture of potassium nitrate, sulphur and carbon in the form of charcoal. In the 19th century, the invention of dynamite by the Swedish chemist and engineer Alfred Nobel gained popularity. Dynamite is an explosive made of nitroglycerin, sorbents such as powdered shells or clay and stabilisers. In essence, dynamites gained popularity owing to its wide-scale use as a safer alternative to gun powder and nitroglycerin alone. Since then, a wide variety of nitroglycerine-based explosives have been produced. Although, they have high detonation velocities and good water resistance, they have high flammability, are highly sensitive to shock and friction and produce large noxious fumes. The most commonly used explosive in mining globally is ammonium nitrate fuel oil (ANFO). It was introduced for blasting operations in the 1950s. Chemically, ANFO is ammonium nitrate mixed with fuel and proper mixing of AN and FO is important for predictable explosive performance.
