Well, you need to build a strong main character. Give them a backstory that makes the readers care about whether they survive or not. Maybe they have a family waiting for them, or they are on a mission that's really important. Then, when they are buried alive, the readers will be more invested. Also, add some twists. Like just when the character thinks they are about to be rescued, something goes wrong and they are in even more danger.
Create a sense of urgency. For example, mention that the air is running out quickly or there are things like water seeping in which will soon drown the character. This will keep the readers on the edge of their seats.
To make it thrilling, use vivid descriptions. Describe the tight space, the smell of the earth, the sound of dirt falling. Let the readers feel like they are in that coffin or hole with the character. And don't forget about the character's emotions. The fear, the desperation, the hope that comes and goes. You can also introduce some external threats like wild animals that might be digging near the burial site, adding another layer of danger to the situation.
