1. Flow Rate The flow rate is a critical factor in determining how efficiently the mud pump operates. It is generally expressed in gallons per minute (GPM) or liters per minute (LPM). The flow rate can be calculated using the formula

2. Rock drill: used to drill holes with a diameter of 20 ~ 100 mm and a depth of less than 20 meters in rocks above medium and hard. According to its different power can be divided into pneumatic, internal combustion, hydraulic and electric rock drill, of which pneumatic rock drill is the most widely used.

Before delving into calculations, it's key to understand how a mud pump operates. Most modern drilling rigs use either triplex or duplex pumps, which use a series of pistons to create pressure. The fluid is drawn into the pump from a storage tank and pumped down the drill string. After reaching the drill bit, the mud carries cuttings back up to the surface through the annulus (the space between the drill string and the wellbore).

Ecologically, spiral foraging promotes responsible harvesting practices. Foragers are encouraged to take only what they need, leaving enough resources for wildlife and for the plants’ own regeneration. The spiral pattern naturally leads foragers away from heavily trafficked areas, allowing plants to flourish undisturbed. By leaving some areas untouched, foragers contribute to the preservation of biodiversity, ensuring that ecosystems remain healthy and resilient.

The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.
