how exploratoring rock drilling is done

Making a hole in the rock necessitates the use of a trusty drill bit—a long metal rod boasting a sharp point at its end. Affixing this bit to a drill, a machine that can rotate it, followed by connecting the tool to a rope to ensure easy lowering in the rock, allows for a successful commencement of rock drilling.

After the initial entry-hole is bored, the drill bit is replaced with a reamer. This specially designed instrument is then linked to a rope which helps guide it into the crevice. Then, this reamer enlarges the incision and widens the gap.

Once the cavity had been broadened, the reaming device was unsheathed and replaced with a different drill bit. This type of bit is known as a core drill and is designed to puncture a hole directly in the middle of the specimen of rock. To ensure precise placement, the core drill was attached to a length of rope with which it was lowered against the rock.

Once the hole is drilled, the core drill is unhitched and replaced with a hammer drill. This type of drill bit is specifically designed to bore through rock. The hammer drill is fastened to a rope which, when lowered, allows it to penetrate the rock and form the desired hole.

Once a hole is cut, the hammer drill is taken away and exchanged for a chisel. This chisel is used to create an opening in the rock beneath. Connected to a rope, it is carefully lowered into the rock’s depths.

A space is formed in the rock after the chisel is carefully lifted away, leaving room for a new tool – the drill. This drill bit needs to be fastened securely then sent down into the depths of the stone, its progress securely monitored by a connected rope. Through precise operation, a hole is created with remarkable accuracy.

With the initial hole in the rock successfully drilled, the drill is removed and replaced with an auger, a different type of bit used to burrow further. This auger is connected to a rope which guides it deeper into the stone as it excavates.

With the auger now absent from the existing drilled hole, it’s time to affix a fresh drill bit. This drill bit is referred to as a core drill, which is purpose-built to penetrate through rock-solid surfaces. It’s also tied to a rope, aiding in its descent into the rocky terrain.

After the necessary hole has been carefully crafted, the core drill is taken off and replaced with a hammer drill. This powerful piece of equipment is responsible for boring through any massive rock formation. It is also fixed to a rope for secure lowering into even the most unreachable spots.

Having completed the first step with the hammer drill, switch out the bit and mount the chisel. This tool is ideal for making the hole in the rock; a rope is added to make sure it can be lowered down safely. Once in position, it is ready to shape the passage, granting access to whatever lies beneath.

Once the cavity had been hewn into the surface with a chisel, a new drill bit was affixed. Called a drill, it was required to puncture the solid stone and in order for it to be done safely, a rope was linked to it. This rope was lowered with the drill into the hole.

Once the drill does its job, it is removed and replaced with an auger, a specialized drill bit. This auger will bore its way through the rock, assisted by a rope to direct its descent into the hard terrain.

After drilling the hole, the auger is detached and swapped for a core drill. This kind of drill bit is specifically tailored to penetrate the rock with a neat hole. Typically, a rope is affixed to the core drill and then gradually lowered into the rock, forging a pathway as it descends.

Once the foundational hole is drilled, the core drill can be detached and replaced with a new drill bit: the mighty hammer drill. It’s lowered into the rock by rope and used to bore a hole into the toughest of surfaces with ease. This unconventional tool applies powerful percussion to break through even the roughest of terrains.

Once the initial hole has been crafted, the hammer drill is extracted and replaced with a new device. This device, referred to as a chisel, is used for further cutting, creating an aperture inside the stone. The chisel is then connected to a length of rope which is used to carefully ferret it into the rock formation.

After hollowing the space with the chisel, it is then discarded in order to initiate a new drilling process.
