During mine excavation, rock wall collapse can pose a safety risk to miners. Reasonably designed support equipment prevent and ensure safe working environment. In this paper, new half-bowl spherical rubber structure is introduced modeled using Abaqus study its damping ability under different impact energies. By comparing the reaction forces pressures of A-S, R-S, C-S structures, we find that R-S structure, with smaller number spheres, has superior energy absorption abilities resistance. These findings designing manufacturing mining equipment.

The well-being of society can be realized through meeting basic needs, one which is providing public infrastructure. This study examines the role Natural Resource Revenue Sharing Funds (DBH SDA) on government investment in infrastructure 491 regencies/cities Indonesia. testing this research uses panel data regression analysis. results show that per capita DBH SDA Indonesia during period 2010–2012 has a significant and positive influence selection based consideration resources boom occurred, where there an increased global demand for natural resource commodities followed by increase commodity prices, thereby positively impacting revenue countries or regions abundant resources. Despite having influence, regional spending tends to more influenced central transfers such as General Allocation Fund (DAU), Special (DAK), Local Own-source (PAD). It was found transfer funds, indicating remains determining expenditure

Underground mines are considered one of the riskiest facilities for human activities due to numerous accidents and geotechnical failures recorded worldwide over last century, which have resulted in unsafe labor conditions, poor health outcomes, injuries, fatalities. One significant cause these is inadequate or nonexistent capacity real-time monitoring safety conditions underground mines. In this context, new emerging technologies linked Industry 4.0 paradigm, such as sensors, Internet Things (IoT), LoRaWAN (Long Range Wide Area Network) wireless connectivity, being implemented planning efficient, safe, sustainable performance mine environments. This paper studies implementation an ecosystem composed IoT sensors LoRa connectivity a data-acquisition system, eliminates need expensive cabling manual mining operations. Laying cables necessitates cable support protection against issues, machinery operations, vehicle movements, operator activities, groundwater intrusion. As expands, additional typically require costly installations unless employed. The results review indicate that LoRaWAN-based sensor network (WSN) provides data under complex effectively transmitting through physical barriers. presents attractive low-cost solution with reliable, simple, scalable, secure, competitive characteristics compared manually collected readings, more sporadic prone error. Reliable on behavior enhances productivity by improving key indicators (KPIs), minimizing accident risks, promoting environmental operators. Finally, adoption information real-time, supports better decisions industry managers, ensuring compliance regulations, productive performance, fostering roadmap towards environmentally friendly conditions.
