Theory and technology of enhanced coal seam gas production by integrated drilling, punching and fracturing in coal mine: Part 1 theory

Abstract Coal seams in China are typically characterized by high coal seam gas content and low permeability, posing challenges for efficient coal seam gas extraction. However, achieving successful boreholes, especially in soft coal formations, remains a challenge. The mechanisms underlying permeabil...
