In geological exploration, Rock Core Sampling quality directly determines the accuracy of exploration data.
However, many contractors face common problems such as broken cores, low recovery rates, sand-filled core barrels, or even empty core tubes.



Based on years of field service experience, XinHao Drilling Rig has found that over 80% of incomplete core recovery issues are caused by improper drilling mud ratios and insufficient hole cleaning, rather than the drilling machine itself.



This guide explains practical, field-proven solutions to help you improve core recovery using the right mud mix and cleaning methods—especially when working with a rock core drilling machine or crawler rig in remote locations.

In geological exploration core drill rig (LEZ) operations, core breakage or detachment directly leads to data invalidation. The primary cause is the selection of the wrong sampler. Mastering the following three selection techniques based on formation, hole depth, and accuracy can improve the average core recovery rate to over 95%.

In mining blast hole drilling, down-the-hole (DTH) drill bit jamming is the number one problem leading to downtime and increased costs. Based on numerous field cases, Xinhao has found that over 60% of drill bit jamming is due to incorrect selection. This article will address this pain point directly, showing you how to significantly reduce drill bit jamming and improve durability by correctly selecting wide-pitch drill bits.

Proper storage is crucial for crawler drill rigs during off-seasons. Without correct maintenance, issues like rusted tracks, emulsified hydraulic oil, and jammed rods can delay your projects. This guide covers essential steps to preserve your crawler drill machine—whether used for gold exploration crawler drill rig, crawler water well drilling, or crawler core drilling—ensuring it starts reliably after months of storage.

In rural well construction, soft soil layers such as clay, silt, and quicksand are the "natural enemies" of drilling rigs. Many farmers and construction teams have reported that after the drilling rig is lowered into the ground, it gets stuck in soft soil, making it impossible to pull the drill rod out. This can delay the project or even damage the drilling tools.

As the holiday season unfolds, we at XinHao Drilling Rig— a leading manufacturer of water well drilling rigs, core drilling rigs, and air-lift reverse circulation drilling rigs etc — extend our warmest wishes to you and your teams.

In mine blasting hole construction, drill bits are the most consumable wear parts – many mine operators report that drill bits need to be replaced on average every 3-5 days, resulting in high wear costs.

The core of geological exploration sampling is to "accurately reflect the original strata," but when serving novice clients, Xinhao Core Drilling Rig has found that 80% of sample contamination and deformation problems stem from negligence in operational details!

As the "core force-transmitting component" of various drilling rigs (such as water well drilling rigs, hydraulic wireline coring drilling rigs, and truck-mounted drilling rigs), the condition of the drill pipe directly determines drilling efficiency and cost. Long-term contact with rock cuttings, mud, and hard rock easily leads to wear, corrosion, or bending, causing stuck drill bits, borehole deviation, and significantly shortening its service life.

The core of geological exploration sampling is obtaining "authentic, complete, and undisturbed" core/soil samples, which directly impacts stratigraphic analysis and engineering decisions. However, in actual construction, problems such as interference from backfill debris, borehole wall collapse in soft soil, and sample loss from sand layers often lead to inaccurate sampling.

If your drilling rig gets stuck, do not panic. For three common scenarios—drill getting stuck in soft soil, hard rock, and backfill blocking the drill—please follow these steps for a quick and safe escape.

Down-the-Hole drill bits are core consumables, directly impacting construction efficiency and costs. Improper selection or improper use of high-quality drill bits can double the wear rate, even leading to stuck drill bits and equipment overload. The core principle is "selecting the right type for the formation and using it according to regulations." The following tips will help you accurately avoid pitfalls and reduce waste.
