Research on Distributing Law and Main Controlling Factors of Tectonic Soft Coal in Hebi Coal Bureau
Phenomena of coal and gas outburst is very seriously in Hebi coal bureau, tectonic soft coal exists nearby the place on which coal and gas outburst happen universally, tectonic soft coal is one of important controlling factors of coal and gas outburst in Hebi coal bureau. Based on analyzing related reference and local practice, using the technology of drill logging curve judging thickness of tectonic soft coal and wireless electromagnetic wave pit detection, combined with underground practical observation during digging coal airway, the author study the distribution characteristics of tectonic soft coal in Hebi coal bureau; During the research, the author adopted a great deal of coal samples during digging coal airway and tested responded primal gas emission velocity and intensity coefficient; Using the theory and technology of gas geology, combined with region and well geological structure characteristics, the author researches distribution law and main controlling factors of tectonic soft coal in Hebi coal bureau, which provides important instruction on later coal and gas outburst prediction and prevention.
