Optimizing roof control using probabilistic techniques in roof failure prediction
… underground mine is the reliable prediction of roof falls' size, frequency and location. Probabilistic simulation of potential roof control problems allows a designer to test the performance of competing mine layouts against assumed roof conditions. By comparing different roof control plans …

Some factors in the use of roof bolts for mine roof control
… of stresses often time cause catastrophic roof-falls which kill and injure miners and damage equipment. Attempts are made to control these unbalanced stresses by choosing the proper method of mining and suitable method of roof support. About 20 years ago, the St. Joseph Lead Company in …

Concepts for retractable roof structures.
… a worldwide increase in the use of retractable roofs for stadia. This increase has been based on the flexibility and better economic performance offered by venues featuring retractable roofs compared to those with traditional fixed roofs. With this increased interest an evolution in retractable …

Analysis of deployable strut roof structures
… These structures are designed to be operable roofs spanning over sports facilities. During deployment, the center of the structure opens or closes to accommodate changes in weather conditions. Building on the geometry established in other work, the relationships between the basic geometric …

Design considerations for retractable-roof stadia
… to replace them with structures with moving roofs. This kind of facility provides protection from weather for spectators, a natural grass playing surface for players, and new sources of revenue for owners. The first retractable-roof stadium in North America, the Rogers Centre, has hosted …

Uplift loaded standing seam roof systems
… the failure of an uplift-loaded standing seam roof system. Four sets of full-scale tests were conducted and their results were analyzed along with previous results (Anderson 1991). It was found that by normalizing the data, a reduction factor could be established for each test set …

Hydraulic characteristics of siphonic roof drainage outlets
Siphonic roof drainage uses an innovative hydraulic design to increase the efficiency ofrainwater disposal. The roof outlet is a critical component of the system and not onlypromotes and sustains priming of the system but also controls the depth of approachflow. This thesis investigates the …

Energy saving potential of various roof technologies
Unconventional roof technologies such as cool roofs and green roofs have been shown to reduce building heating and cooling load. Although previous studies suggest potential for energy savings through such technologies, many factors affect potential savings. To further investigate these factors, a …

Structural performance of spoke wheel roof systems
A spoke wheel roof system consists of tension rings, compression rings, and radial spokes and resists loads mainly through axial forces. Due to its light weight and ability to achieve a column-free, long span, it has been a popular solution to structures such as stadia since its first use in 1960s. …

Geologic feature prediction using roof bolter drilling parameters
The design of a safe and efficient roof support system is essential for any underground coal mining operation. All underground coal mines in the United States install roof bolts with a roof bolter as the primary means of supporting the mine roof. Proper application of roof bolting is dependent upon …
