VERTICAL PIT DESIGN Sample Clauses

VERTICAL PIT DESIGN. The Koidu vertical pit mining project was characterized by a unique set of circumstances comprising political, social, geographical and administrative challenges. A highly detailed design process with large numbers of boreholes and multiple sets of laboratory tests, followed by of the required design work was not financially feasible, nor practically possible. The decision was made to base the design on the information already collected during the earlier open pit feasibility study, with an additional site visit to audit the core logs and give the designers a better feel for the geology of the country rock surrounding the pit. The design of the vertical pit excavation was carried out using various calculation approaches to ensure design integrity. The material parameters were obtained by back analysis of the existing highwall at the No. 1 Pipe, excavated during previous mining attempts, and using the ▇▇▇▇-▇▇▇▇▇ failure criteria based on the laboratory tests and core logs. The design calculations comprised limit equilibrium, 2-dimensional and 3-dimensional numerical modeling. The results obtained from each of these methods were ranked according to stability and a final design decision made. 3.1 ROCK MASS STRENGTHS – The design rock mass strengths were selected based on the back analysis of the existing highwall and the ▇▇▇▇-▇▇▇▇▇ failure criteria (▇▇▇▇ et al., 2002). In addition to the normal factors incorporated by the ▇▇▇▇-▇▇▇▇▇ failure criteria, the following factors were considered subjectively: • Additional confinement provided by the constrained geometry of the vertical pit sidewalls; • The small scale of the vertical pit in terms of cross-sectional area and height; and • Time related degradation of the rock mass strength through creep and strain softening. The final design parameters based on the above evaluation were: Material Cohesion (kPa) Friction Angle (°) Tensile Strength (kPa) Granite Rock Mass 800 41 70 Granite Joints 0 41 0 As these parameters included many subjective components that may have changed with time once mining commenced, these parameters were based on the following design assumptions: • Effective pit limit blasting; • Effective dewatering of the pit sidewalls; • Ongoing monitoring of the pit sidewalls to give warning of unacceptable sidewall displacement and possible sidewall collapse; • A maximum mining life of 3 years from start to completion to limit the time dependant changes in rock strength; • Vertical sidewalls or flatter,...

  • Project Design Applicants must design a project that provides access to health services to enable eligible women and men experiencing health needs to secure and maintain safe and accessible quality screening and diagnostic services, comprehensive family planning, and/ or other women’s health services. A. Applicants are encouraged to emphasize the following components in the design of their projects. Projects must: 1. Use a collaborative approach to maximize existing community resources and avoid duplication of effort; 2. Enhance systems and local processes to make it easier for people to transition to, from, and between services; 3. Address barriers to ensure services are accessible to people regardless of setting or location; and 4. Promote improvement and positively impact health and well-being through coordinated service delivery. B. To be effective, services and activities provided or made available as part of the Proposed Project should have policies and procedures in place and include with the application as an attachment that: 1. Delineate the timely provision of services; 2. Deem Client eligibility and service provision as soon as possible and no later than 30 calendar days from initial request; 3. Require staff to assess and prioritize Client needs; 4. Implement with model fidelity to an evidence-based program or based upon best available research; 5.

  • EPP query-­‐command RTT Refers to the RTT of the sequence of packets that includes the sending of a query command plus the reception of the EPP response for only one EPP query command. It does not include packets needed for the start or close of either the EPP or the TCP session. EPP query commands are those described in section 2.9.2 of EPP RFC 5730. If the RTT is 5-­‐times or more the corresponding SLR, the RTT will be considered undefined.

  • Schematic Design Documents In accordance with the approved Preliminary Design and Construction Schedule and based upon approval of and comments made by the Owner regarding the Concept Design Studies, the Design Professional shall prepare and submit to the Owner Schematic Design Documents, including drawings and outline specifications. These documents shall represent a further development of the approved design concept, providing additional detail and specificity regarding the intended design solution. Typically, all such documents shall be drawn to scale, indicating materials and assemblies, as appropriate, to convey the design intent and to illustrate the Project’s basic elements, scale and relationship to the Site. All major pieces of furniture and equipment to be fixed or supplied by the CM/GC shall be illustrated to scale. (See ASTM Standard Practice E 1804-02, August 2007, Sections 6.3, 8.2 and 8.3 for guidance on information which is generally developed in Schematic Design.)
