History of coal mining - Wikipedia

The technology was far in advance of any coal mining method in the late medieval period and was considered one of the industrial wonders of the age. During the 17th century a number of advances in mining techniques were made, such the use of test boring to find suitable deposits and chain pumps, driven by water wheels, to drain the collieries.

Longwall mining - Wikipedia

The basic idea of longwall mining was developed in England in the late 17th century. Miners undercut the coal along the width of the coal face, removing coal as it fell, and used wooden props to control the fall of the roof behind the face. This was known as the Shropshire method of mining.

Research on Non-Pillar Coal Mining for Thick and Hard

This article introduces a new non-pillar coal mining technology (i.e., Gob-side Entry Retaining by Roof Cutting (GERRC)) under the condition of thick and hard roofs. First, we theoretically analyzed the solution to the large suspension span of the thick and hard roof in coal mining. Three-Zone pre-split blasting design in non-pillar coal mining for thick and hard roofs was proposed, based on
