Overbreak is a detrimental phenomenon caused by tunnel blasting, which can lead to
increased time and cost in the construction schedule. It is very important to establish a model …

Drilling and blasting is a common excavation method in underground engineering. In
modern mine construction, improving the efficiency of rock roadway excavation is a …

Sustaining wellbore stability in depleted reservoirs is a crucial concern. With production from
hydrocarbon reservoirs, the reservoir's pore pressure is reduced over time, and the reservoir …

Over the past several decades, raise excavation has been widely employed in underground
mining, civil engineering and military engineering. One-step raise excavation with burn cuts …

Drilling and blasting methods have been used as a common driving technique for shallow-
hole driving and blasting in rock roadways. With the advent of digital electronic detonators …

Drilling and blasting method have been widely used for driving tunnels in hard rock. When
designing a blast operation especially in case of long tunnels, the primary objective of …

To control the overbreaking of an underground mining development gallery, the controlled
blasting technique was proposed and as a result it was possible to reduce costs and …

The Karadon mine, where field studies were carried out, is located in the north west of
Turkey and is considered to be a highly gaseous coal mine. Explosives and ignition systems …

In this study, the mechanism of cracking under the coupling effect between the use of
shaped blasting and deployment of empty holes was explored through theoretical analyses …

Cut blasting, a critical aspect of single-sided blasting in underground rock engineering,
significantly influences tunnel excavation speed. This study investigates the characteristics …
