### Get Intervals Below Depth with Product

Source: https://help.maptek.com/blastlogic/2025.2/topics/quick-reference/charge-rule-api/object-interfaces

Returns a list of intervals for decks containing specified products that extend below a given depth. An optional tolerance can be provided to extend the interval slightly above the depth, preventing the splitting of decks if they only partially overlap the depth. This is useful for selecting explosive products below a water level for replacement.

```javascript
hole.productsBelow(products, depth, tolerance=0)
```

### Get Total Explosive Mass

Source: https://help.maptek.com/blastlogic/2025.2/topics/quick-reference/charge-rule-api/object-interfaces

Calculates and returns the total mass of explosives, in kilograms, that have been allocated to the hole up to the current point.

```javascript
hole.totalExplosiveMass()
```

--------------------------------

### Get Unallocated Interval

Source: https://help.maptek.com/blastlogic/2025.2/topics/quick-reference/charge-rule-api/object-interfaces

Returns an interval representing the portions of the hole that have not yet been assigned any product. This identifies areas available for further allocation.

```javascript
hole.unallocated()
```

### Calculate Average In Hole Density (Blast Product)

Source: https://help.maptek.com/blastlogic/2025.2/topics/quick-reference/charge-rule-api/object-interfaces

Calculates the average in hole density (kg/m^3) for a gassed product at a specified depth. Requires a density table to be added to the Blast Product Catalogue. Throws an error if no density table is provided.

```BlastLogic Script
product.averageInHoleDensity (depth,openCupDensity)
```
