Title: David A. Whitley: Innovator in Mining Technology
Introduction
David A. Whitley is a notable inventor based in Brea, California, recognized for his contributions to mining technology. He holds a total of 3 patents that focus on improving the efficiency and safety of mining operations. His innovative approaches have made significant impacts in the field.
Latest Patents
Whitley's latest patents include groundbreaking technologies such as blind shaft drilling and mine shaft liners. The blind shaft drilling patent addresses the challenges of mining various minerals from the earth by utilizing large diameter bore hole drilling equipment. This method allows for the creation of deep shafts, exceeding 10 feet in diameter and reaching depths of at least 2000 feet. The drilling operation employs reverse circulation to remove broken fragments, while non-rotating stabilizers ensure proper alignment of the drilling bit. Additionally, maintaining fluid levels in the drilled hole creates hydrostatic pressure, preventing inflow of water and debris.
His mine shaft liner patent focuses on the necessity of drilling deep bore holes, typically between 3000 and 6000 feet. To protect miners entering these holes, specially constructed lining segments made of prestressed concrete or steel are used. These segments are lowered into the bore hole to create a protective stack, with guide cables ensuring proper orientation during the process. Grouting is performed periodically to secure the segments in place, allowing miners to safely enter the bore hole for further operations.
