[Abstract] 
Problem Statement:
fiogf49gjkf0d
Mitigation of a massive sandstone channel's impact on a wide longwall face
Objective of the Paper:
fiogf49gjkf0d
To illustrate the effectiveness of the hydraulic fracturing technique and the LVA software
Key Findings:
fiogf49gjkf0d
Creation of multiple horizontal fractures and correct predictions of longwall face cavities
Key Conclusions:
fiogf49gjkf0d
Horizontal fractures created by the hydraulic fracturing technique serve to relieve the cantilever compressive stress at the longwall face. The LVA software correctly predicts the majority of cavity formation at the longwall face
