Introduction

Gary Drinkard is a notable inventor based in Houston, TX (US), recognized for his contributions to coal mining technology. He holds a total of 4 patents that focus on innovative processes for extracting and treating coal. His work has significantly impacted the efficiency and effectiveness of coal mining operations.

Latest Patents

One of Drinkard's latest patents is titled "Process for forming a coalate solution in-situ." This invention outlines a method for mining underground coal formations with high oxygen content. The process involves contacting the coal with a heated basic aqueous solution, allowing for the dissolution of a portion of the coal to produce a coalate. To enhance access to the coal formation, some of the dissolved material is periodically or continuously removed. The dissolved coal is then treated with a regenerating agent to recover the basic aqueous solution.

Another significant patent is "Coal disaggregation by basic aqueous solution for slurry recovery." This invention describes a process for treating underground coal formations by using a basic aqueous solution to disintegrate the coal. The disintegrated material is then removed to create permeability in the coal formation. Following this, the coal is treated with a heat-carrying fluid to recover energy values. Additionally, this patent includes a process for slurry mining coal, which involves forming a slurry by contacting the coal with the basic aqueous solution.
