Core offering

Simplified Mine Instruments designs and manufactures rugged mechanical and mechanical-plus-digital ground movement monitoring instruments for underground mining and tunneling operations. The product line consists of the SAG Flag Roof Monitor (continuous visual roof sag indicator), the MHL Miner's Helper Extensometer (single-point rock movement detection), and the MHR3 3-Point Extensometer (multi-depth strata monitoring), each available with optional Bluetooth data-logging adapters that export to mobile app and CSV. The company also sells custom solutions, data interpretation and graphing services, and is developing a Mesh Network Data Logger for real-time wireless underground monitoring.

Product overview

Simplified Mine Instruments provides a focused portfolio of ground movement monitoring instruments for underground mining and tunneling operations. The core product line consists of three instrument families: SAG Flag Roof Monitors, MHL (Miner's Helper Extensometer), and MHR3 (3-Point Extensometer). The SAG Flag and MHL serve as visual monitoring tools with reflectorized indicators for continuous roof movement indication. The MHR3 offers multi-point monitoring for detailed strata analysis. Each instrument family is available in base versions and with optional data logging adapters that enable Bluetooth connectivity and mobile app access for automated data collection and CSV export. The company also offers data interpretation and graphing services, and is developing a Mesh Network Data Logger for real-time wireless monitoring.

Products and services

• SAG Flag Roof Monitor Roof monitor for underground mining operations that provides continuous visual indication of rock movements from a few feet into the rock to 50 feet or more, via a reflectorized flag and scale on the plunger. Features stainless steel body and anchors for harsh mining environments.
• SAG Flag Roof Monitor W/ Adapter SAG Flag with built-in Bluetooth data logging via SF-Adapter. Measurements are automatically recorded and accessible through a mobile app via Bluetooth connection, with CSV export for reporting and analysis.
• MHL (Miner's Helper Extensometer) Single-point extensometer for underground mining that tracks rock movement at custom depths using a durable fiberglass rod. Features a 12-inch reflectorized drop flag providing highly visible alert when preset trip point is reached. Made from non-corrosive Acetal Copolymer, fully adjustable and resettable with 25mm movement range.
• MHL W/ Adapter Same reliable performance as the original MHL with added built-in Bluetooth data logging via the MHL-Adapter. Measurements are automatically recorded and accessible through a mobile app via Bluetooth connection, with CSV export capability.
• MHR3 3-point extensometer that captures rock movement at multiple depths using three rods positioned to detect delaminations at distinct horizons. Designed for deeper insight into layered roof behavior; when paired with a data logger such as the Onset HOBO MX1105, readings can be retrieved via mobile app and saved or shared as CSV files. Features 25mm movement range per point and 1.5-inch minimum hole diameter.

Partnerships

Two partnerships are on record, tiered core.

• Carroll Technologies GroupcoreChannel Partner/ Reseller/ Distributor · 1 January 2022Strategic partnership formed in 2022 for distribution of SMI instruments across the United States. Carroll Technologies Group serves as the primary US distributor, providing sales and distribution infrastructure for Simplified Mine Instruments products.
• HOBO (Onset Computer Corporation)coreTechnology or IntegrationIntegration partnership with HOBO MX1105 Bluetooth-enabled data logger. SMI instruments connect with displacement sensors that output voltage signals logged by the MX1105. Data scaled to linear movement readings using HOBOconnect or HOBOware software.

Broad incumbents

• Hexagon Mining: Hexagon's Mining division offers a broad portfolio of mine planning, fleet management, surveying, and safety monitoring solutions including geotechnical monitoring tools. A broad incumbent whose portfolio overlaps with SMI's monitoring focus but at much larger scale and scope.
• Carlson Software: Carlson Software provides surveying, GIS, and mine design software with associated hardware. Its mining-focused products include instrumentation and monitoring workflows, positioning it as a broad incumbent adjacent to SMI's niche.
• GroundProbe: GroundProbe (Orica) provides slope stability radar and geotechnical monitoring solutions for open-pit and underground mining. While its primary focus is slope stability radar, it is a broad incumbent in the mining geotechnical monitoring category overlapping with SMI's ground movement monitoring scope.
• Maptek: Maptek offers mining technology including 3D laser scanning, geological modeling, and slope stability monitoring. Broad incumbent in the mining technology space with overlapping geotechnical monitoring capabilities versus SMI's focused instrument line.

Direct peers

• Geokon: Geokon designs and manufactures geotechnical instrumentation including extensometers, strain gauges, and load cells for mining, tunneling, and dam monitoring. Directly comparable as a specialist manufacturer of in-ground monitoring hardware for similar end markets.
• RST Instruments: RST Instruments manufactures geotechnical and structural monitoring instruments (extensometers, inclinometers, piezometers) used in mining, tunneling, and civil engineering. Directly comparable to SMI's extensometer/roof monitor product line with similar underground monitoring focus.
• Roctest (Nova Metrix): Roctest designs and supplies high-precision geotechnical sensors and instruments (extensometers, pressure cells, fiber optic sensors) for mining and civil engineering. Direct peer in specialty underground and ground monitoring instrumentation.
• Durham Geo Slope Indicator (DGSI): DGSI provides geotechnical and structural monitoring instruments (inclinometers, extensometers, tiltmeters) for mining, tunneling, and civil infrastructure. Comparable niche manufacturer serving overlapping ground movement monitoring applications.

Emerging players

• Worldsensing: Worldsensing provides wireless IoT monitoring solutions for mining, construction, and infrastructure, including tiltmeters and geotechnical sensors. Emerging player in connected/IoT mining monitoring that intersects with SMI's evolving mesh network data logger roadmap.
• Sensemore: Sensemore offers AI-driven industrial asset monitoring (vibration, temperature) with focus on predictive maintenance. Adjacent emerging player in industrial condition monitoring that could extend into mining ground/structural monitoring with similar IoT data logger architectures.
