The response of porosity properties of low-grade coal reservoirs to Magma invasive--Taking Shandong Qiwu mine for ezample

摘要：

Qiwu Mine Belonged Tengxian coal withstand repeated volcanic activity, magma intrusion more serious. In this paper, a detailed analysis of regional, mine structures and magmatic activity,combinesing with the experimental means of quantitative measurement of macerals, pressure mercury pore structure testing and isothermal adsorption. Authors think that magma intrusion in low rank coal, with the distance from the magmatic rocks of the narrow pores of the coal increases, but the vicinity of magmatic rocks in the abnormal region will decrease rapidly increasing.
