Cost Analysis of Bulkhead Refuge Chambers Using Data Provided by Foster-Miller

摘要

This cost analysis evaluates the industry cost of the bulkhead type of refuge chambers which are constructed underground within the coal mine. The cost estimates are provided by Foster-Miller, Inc. and are shown in Appendix A and Appendix B. All the assumptions made for generating these costs can be found in the report by Foster-Miller; Cost Estimates/Comparisons for Refuge Types. The general assumptions that were reported in the Cost Analysis of Portable Refuge Chambers, are also applied to the bulkhead chambers. Differences in cost estimates occur with the purchase and installation, maintenance and inspection, and move costs.
