THEORETICAL RESEARCH ON REASONABLE SHIELD SUPPORT CAPACITY IN CLOSE-MULTIPLE COAL SEAMS WITH THE COORDINATED MINING: A CASE STUDY OF QIANJIAYING COAL MINE.

In order to assess the rationality of the rated shield support capacity (RSSC) experienced selection and guide the reasonable RSSC selection for the subsequent working faces of each coal seam, the coupling relationship between shield and roof strata was revealed during each coal seams mining.According to whether the fractured rock blocks generated

PURPOSE This study aimed to develop a positive psychological intervention program for a college ice hockey team and test its effects based on application to the plantar Fasciitis team.METHODS The demands of 78 college ice hockey players were asked through open questionnaires.Collected results underwent integrated analysis to develop the desired pro

The study of the combination of chemical kinetics with transport phenomena is the main step for reactor design.It is possible to deviate from the model behaviour, the cause of which may be fluid channelling, fluid recirculation, or creation of stagnant regions in the vessel, by using a dispersion model.In this paper, the known general solution of t

The motion of nonholonomic mobile manipulators (NMMs) is inherently constrained by joint limits, joint velocity limits, self-collisions and singularities.Most motion planning algorithms consider some of the aforementioned constraints, Shower Oil however, a unified framework to deal with all of them is lacking.This paper proposes a motion planning s
