In order to reduce the occurrence of drilling accidents in soft coal seams, this paper analyzes the causes of near-horizontal hole drilling under the coal mine and the formation process of jamming, and establishes a drilling mechanical model for each stage.Through the analysis of the main influencing factors of the sticking drilling, it is conclude
A comprehensive understanding of the characteristics of the road network is imperative for implementing fundamental Set measures to enhance traffic efficiency and mitigate delays.The objective of the present study is twofold: firstly, to classify the urban street network in the city of Karbala; and secondly, to evaluate its effectiveness.Following

In this paper, we dene the concepts of commute proximally, dominate Receivers prox- imally, weakly dominate proximally and common best proximity point in fuzzy metric space (abbreviated, FM-space).We prove some common best proximity point and com- mon xed point theorems for dominate proximally and weakly dominate proximally map- pings in FM-space u
