Underground mining equipment handles the extraction side of a project, before ore reaches the process plant. Core drilling rigs recover continuous rock cores for exploration and grade definition, while LHD (load-haul-dump) loaders muck and transport broken ore in confined headings. Xinhai supplies both, sized to drilling depth and bucket capacity for your operation.
Underground mining equipment sits upstream of mineral processing, in the mine itself, where the orebody is defined and broken ore is moved to the surface or to a ore pass. Reliable extraction equipment underpins a steady feed to the plant: exploration drilling fixes where and how much ore exists, and mucking and haulage units move it efficiently through tight underground headings. Machines for this duty are built compact and rugged, with diesel power and tight turning for confined spaces.This hub carries two essentials. The diesel core drilling rig recovers continuous cylindrical rock cores for geological logging, assay and resource estimation, with depth capability that can reach several hundred meters depending on rod string and configuration; it is the workhorse for exploration and grade-control drilling. The underground LHD loader is a low-profile load-haul-dump machine that scoops broken ore at the face, tramming it to a truck, ore pass or stockpile, with bucket capacity selected to match heading size and required mucking rate.Selection depends on the task: drilling rigs are chosen by target depth, core diameter and hole angle, while LHD loaders are chosen by bucket size, heading dimensions and haul distance. These units determine what and how much ore reaches the plant, so their capacity should be planned against plant throughput. Once mined ore arrives at surface, it enters the crushing circuit and then the full concentration flowsheet, which Xinhai can deliver as a complete mineral processing plant.Core diameter is a balance worth thinking through: larger cores give more sample for assay and better geotechnical data but drill slower and cost more per meter, while smaller cores reach greater depth and move faster, which is why exploration programs often step down in core size as a hole deepens. For mucking, a sound planning figure is to size the LHD so its bucket payload and cycle time comfortably exceed the daily tonnage the plant must be fed, leaving headroom for ramp gradients and tramming delays. Diesel units need adequate ventilation, so heading design and machine emissions are matched. Planning extraction capacity a step above nominal plant feed is the simplest insurance against the mine becoming the bottleneck once the concentrator is running at design rate.For how mine and plant fit together under one contract, see our overview of a mineral processing EPC project.

What drilling depth can a core drilling rig reach?
Diesel core drilling rigs can reach from tens of meters up to several hundred meters depending on the model, rod string and core diameter chosen. Smaller-diameter holes go deeper for a given rig. We match the rig to your target depth, core size and hole angle so it recovers usable, continuous core for logging and assay.
How do I size an underground LHD loader?
An LHD is sized by bucket capacity, which must suit your heading dimensions, the required mucking rate and the haul distance to the dump point. A low-profile machine is essential for tight headings. We help match bucket size and machine width to your tunnel cross-section and tonnage targets so mucking keeps pace with production.
Is this equipment suitable for small underground mines?
Yes. Both the core drilling rig and the LHD loader are available in compact configurations suited to small and medium underground operations with limited headroom and tight development. We can advise on right-sized machines so capital and operating cost stay proportionate to your production rate rather than over-specifying.
Can you supply mining and processing equipment together?
Yes. Under the EPC+M+O model Xinhai can supply mine extraction equipment alongside a complete processing plant, coordinating mining capacity with plant throughput so feed is steady. This single-source approach simplifies procurement and ensures the mine output matches what the concentrator is designed to treat. Contact us with your project scope for a combined proposal.
