In modern room and pillar coal mines, the coal is produced by continuous miner (CM) machines. The CM is used to mine the coal seam by continuously cutting at a vertical face. Depending on the seam thickness, quality, and geotechnical proper...
Evaluating fracture volume loss during production process by comparative analysis of initial and second flowback data [0.03%]
通过初始流回和二次流回数据的比较分析评估生产过程中的压裂体积损失
