1. IntroductionDue to old age and lack of maintenance, the roadway’s surrounding rock deformation and damage are serious. During the mining period—especially in the vertical distribution with the working face towards the abandoned roadway—the surrounding rock of the abandoned roadway has difficulty withstanding the influence of the working face over the front support pressure and the phenomenon of roof fracture, which are two types of instability.

So Im changing plugs in my car. I started with cyl 1 and it was REALLY tight. With just the 3/8" ratchet I got it about 1 turn and stopped. Going about 1/8 turn at a time. Something was not right. I went to the next cyl to see if it was as hard. It was tight but not like the 1st cyl. I tried the other 4 and they were all tight. I got some Liquid Wrench and put some drops down each and let it sit for about an hour. Came back and did the 1/8 turn back and fourth to work the LW in a bit.

So I just started doing a few things under the hood. Car is a 2015.5 XC60 T6 3.0. I noticed I has a bit of oil spray on the Air outlet tube where the little elbow hose from the Oil Trap cover is. Looking closer it was cracked and not connected to the Air outlet. Also it seems someone tried to glue it back in place and it failed at some point, who knows when? Does anyone know what this exactly does and what issues it can cause if left that way. Asking because I don't know how long it's been this way.

1. IntroductionChina possesses substantial coal reserves and has traditionally relied on coal as its main energy source. The progress of the coal industry is crucial for the nation’s economic growth [1,2]. Nevertheless, the coal industry faces a range of obstacles, including water, fire, gas, and roof collapses during mining, limiting its development.
