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.

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.

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.
