Engineering Support for Start-up of Large Underground Coal Operation—Trinidad, Colorado Starting in 2009 and continuing into 2011, Agapito Associates, Inc. has provided most of the mining engineering services required to bring this large underground, multi-seam coal mining operation into production. At full production, the New Elk Coal Company mining complex is scheduled to produce over [...]
Solution Mining of Trona Eti Soda, Inc. is developing the Beypazari trona deposits in Turkey. AAI has been involved since 1999 in various projects. Initially AAI reviewed plans for underground mining the southern portion of the deposit. This involved review of geologic, geotechnical, and geo-hydrology to assess reserves; mine productivity; ventilation; and capital and operation [...]
A longwall feasibility study was performed, including review of geologic and geotechnical data, determination of longwall panel orientation, gateroad design, mains, barrier pillars and start-up/recovery rooms, and shield capacity. In-situ stress measurements and strength testing were performed, and a ventilation analysis was conducted. Agapito Associates, Inc. (AAI) conducted geotechnical investigations in support of the planned construction [...]
PB Energy Storage Services, Inc. AAI has been involved with nearly all phases of the design and construction of an underground gas storage cavern located near Huntington, West Virginia. The overall project is being undertaken by PB Energy Storage Services, Inc., of Houston, Texas. AAI first became involved with the project in 2005 through cavern [...]
Maiden Rock Mine Resistance Ventilation Designs Fairmount Minerals’ Maiden Rock underground sand mine historically delivered air to ventilate diesel-powered equipment at its working faces through high-resistance, 380-mm-diameter (15 inch) PVC distribution lines. In support of plans for expanded production, three new, low-resistance ventilation design alternatives were analyzed. The study determined that adequate ventilation for expanded [...]
Dynatec/Middle Tennessee Zinc The MTZ mines utilize random room-and-pillar mining method that results in complex ventilation networks. Upon decommissioning, the mechanical ventilation units were removed and disposed of and several shafts sealed. In an effort to re-open the mines and operate in compliance with the Mine Safety Health and Administration (MSHA) diesel particulate matter (DPM) [...]
PB Energy Storage Services, Inc. Developed detailed ventilation simulations using VnetPC2007 for the construction progress on a weekly basis. Simulations were used for decision making in the design stage for consideration of ventilation control device sequencing and management of air quality and quantity.
Agnico-Eagle Mexico, SA de CV AAI prepared estimations of future ventilation fan requirements and ventilation control locations using the simulation package VnetPC2007 for the Agnico-Eagle Pinos Altos Mine. The mine is located in the Sierra Madre gold belt approximately 280 km from Chihuahua, Mexico, and is actually two interconnected mines: the Santa Nino and the [...]
BRS/Uranium One, Inc. AAI performed a series of mine ventilation analyses to facilitate the proposed mine operating in compliance with applicable air quality regulatory standards. Particular emphasis in the design was placed on the main fan and raise locations that should, with appropriate controls, enable the mine to meet applicable Mine Safety Health and Administration [...]
Numerous projects have been performed for Andalex. A technical review and recommendations were presented on the feasibility of converting mining operations in three seams from room-and-pillar to longwall. The project included reviews of the geologic setting, lithology, structure, and longwall mineable reserves, as well as evaluation of mine ventilation plan, methane control, ground control plan, [...]
