Toward this end, this paper presents a case study in Ningqiang County, ,Shanxi Province,, China. Slope units were selected as the basic mapping units. A traditional statistical certainty factor model (CF), a machine learning support vector machine model (SVM) and random forest model (RF), along with a hybrid CF-SVM model and a CF-RF model were applied to analyze landslide susceptibility.

Results indicate that the ,fracturing fluid, filtration has a great impact on the ,flowback, performance and later gas prodn. Results suggest that increasing the filter cake thickness decreases the gas prodn. peak value, and delays the time showing the peak of gas prodn., and further reduces the cumulative gas prodn.

The engineering data is from Jincheng 1# test well of ,Shanxi province,, China. The No. 3 seam experiences single coal seam development, whose mineral depth is from 521.6 m to 527.4 m, the minimum horizontal stress on the main seam tested by hydraulic ,fracturing, is 7.9 MPa~9.4 MPa, and the maximum horizontal stress determined from long spacing sonic and coal reservoir fracture pressure is …

This winter and spring, the reservoir was the capital’s lifeline. No rain or snow fell in Beijing between October 23rd 2017 and March 17th 2018—by far the longest drought on record. Yet the city suffered no supply disruptions, unlike ,Shanxi province, to the west, where local governments rationed water.

The roundness of coal fine particles ranges from excellent to poor in the order of bailing coal fines, pipeline filter coal fines, ,flowback, coal fines, and drilling cuttings. However, the sorting of drilling cuttings is excellent, and the particle edges are straight, neat, and smooth, while the sorting of bailing coal fines is poor, and the particle edges are curved, uneven, and rough.
