ABSTRACT

The design and construction of wine caves can be difficult due to low ground cover, weak rock or soil, presence of sand and complicated by the elaborate curves and labyrinth-style floor plans. This paper will focus on southern California’s first wine cave in the Temecula wine region that was constructed by mining techniques. An excavation procedure was needed to reinstate tunneling excavation at the Oak Mountain Winery in Temecula, CA USA after a fallout with an estimated 6.1 meter diameter and 6.71 meters overburden. Sandy soils with low cohesive properties and low saturation have created difficult tunneling and safety conditions. The proposed excavation sequence was divided into four stages using spilling if needed until less sandy or stronger material was encountered The following analyses were performed to provide supporting calculations and information to provide safe tunnel excavation conditions as required by mining regulatory oversight. Analyses using cellular concrete for fallout conditions were also modeled. Results, recommendations and conclusions are presented.
