#0183;#32;Drilling and blasting are the two most significant operations in open pit mines that play a crucial role in downstream stages. While previous research has focused on optimizing these operations as two separate parts or merely in a specific parameter, this paper proposes a system dynamic model (SDM) for drilling and blasting operations as an interactive system.

#0183;#32;1. Introduction. Drilling and blasting play vital roles in open pit mining. These operations do not only affect the cost of production directly but as well the overall operational costs .The penetration rate prediction is a necessary value for the cost estimation and the planning of the project.
Openpit mining, also known as opencast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an openair pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks

#0183;#32;Openpit mining uses large holes in the ground that are excavated to the depth of the desired product, and are common for sand, gravel and copper mines. Mining machines called draglines use a moving bucket to scrape away the soil lying over the ore deposit. Draglines can move the soil to a waste pile away from the pit, or dump the material into large trucks that transport it away from the site.

Some mining machines are used to transport mining or workers (miners), you can also use machinery to introduce explosives with a longitudinal arm making the explosion more effective. Other types of mining machinery are used to introduce the concrete into the wall of the rock making it more consistent and safer. open pit mine
ADVERTISEMENTS: In this article we will discuss about the types of drilling methods used in mining. The types are: 1. Percussive Drilling 2. Rotary Drilling. Method # 1. Percussive Drilling: In this method which is the oldest one of drilling, the hole is drilled by striking a number at
